Anyone had a torsion bar slip out of the LCA or pork chop? What causes it?

Has to be something fairly bad wrong for that to happen., like the pork
chop crossover bolts that attach it to the side frame rails loose or lost,
or the lower control arm torsion bar socket stripped out, or lower control
arm bushings totally shot or the bolts missing, etc.

I have seen that twice. In both cases the Lower Control Arm bushings were badly worn and the bar was stuck in the lower control arm. Both of them pulled out of the pork chop. I have also seen where the torsion bar spun or slipped in the LCA socket.
I believe Colonel ken had one slip out of the pork shop.

Well we had one today.... Marjon, my wife was shaken by the very, very loud BANG it made and the drop the coach made on the right front instantly!
To tell the whole story. We never had any problems had like that, not on normal not on BLM
Land like access roads.
We went yesterday to Applied to ask them to look over my steering, level height and front height ( especially right side was low!)
They checked out all of that and Jim who was supervising his mechanics started with leveling the back, used my Schräder valves to level it, used fixed wooden blocks at a specific length for the Rear and Back.
Then they went to tighten the front torsion bar especially right side, it was lower. They used the unloader tool but still those young guys where wrestling with a long bar to get the needed 10 turns more tight, left side only two were necessary.
Now the GMC was with the blocks under the frame exactly on its factory heights specifications !
Excellent!
Because it was late we could spent the night at the Applied RV Resort .... LOL
And in the morning after breakfast I needed some more stuff, not only for myself but also European friends, bought them, chatted a bit with Nick and Jim and of we went to do some shopping and wanted just to make turn towards the Walmart, a very loud BANG and a quick drop on the right front made me stop instantly.
Looking outside it dropped significantly! Luckily I could drive it very slowly, no dragging en we weren't on the highway so back to Applied.
At first the mechanic had to get it back to some height, otherwise we could not even go on the Ramp.
At first he thought the end of the bar was crushed! But later on it was clear, it slipped, popped out ...
Well we needed a new pork chop and they reassembled it. But on Saturday a new leveling and adjusting was not possible anymore, so for now we could still stay at the Applied RV Resort (no where any vacant campground spots ...SF has his fly an ships festivities!)
We have to wait till Monday, then leveling and adjusting will be done, once again.
And the next day, by a Tire/Alignment shop nearby and who does more GMC's for Jim, we go for an alignment.
We also replaced that old still original steering damper for a new one .....
My question, if the torsion bar is not fully in place and one thightens a bolt, that many turns, despite the unloader tool, can you actually force it almost out of its normal position so during the next ride it can "pop out" ... ?
Bye, Daniel,
Still on our Fall trip from Tucson, over LA to Canyonville, OR, GMCWS Rally, now back over Redding and currently in Fremont, CA ... heading Fresno, Bakersfield, Barstow, VoF, Las Vegas and then Lake Havasu City ....

That is something that no one would normally check. The rear end of the bar should be almost all the way back in the cross member frame but not touching it. There is spec on it that I do not remember. What I said in the previous posting is if you have worn lower control arm bushings then there can be a slight amount of forward and backward movement on the bar as you accelerate and decelerate. Over many hundreds or ever thousands of cycles the movement can pull that bar put of the pork chop.
I never ever lube the pork chop socket. The should never be any movement there. While it is hard to see there, If you do see rust coming out of the socket then there is movement.
I do liberally lube the LCA socket on the other end of the bar hoping that if there ever was any movement it would only be on that end and not move the bar.

I second what Ken says, and add this: torsion bars are a coil spring that
never got wound up. They are made from spring steel, a special alloy that
has the microscopic inner structure of a rubber band. They were originally
engineered to support the static load of the front of the gross vehicle
weight, plus the dynamic loading of pitch and yaw and braking weight
transfer from the coach, and to resist the shock loading that occurs from
irregularities in the road.
And they have done their job very well for far longer than any
engineering team could have forseen.
Some of the abuse they have encountered during their life cycle have
been quite severe, not the least of which is jacking up the entire front of
the coach with a floor jack.
They also posses properties not dissimilar to those of a rubber band.
They can endure their original design stresses quite well, but, stretched
too far only a few times and their yield strength limit is
exceeded, and failure is imminent.
The original parts supply resided with dealerships and GM parts
depot's. Never in large supply. If there are still any of them out there,
Cinnebar more than likely has them. Out here in the Wild Western Frontier,
they might as well be on the moon.
So, Peter Huber in California, contacted a spring manufacturer and
had small batches of bars created that were 19% stronger than the original
specs to compensate for the propensity of today's coach owners to overload
the hell out of their rigs. Don't know if he still has any, but I still
have 5 sets, 4 of which were made with the hex on one end longer to engage
more of the socket in the lower control arm.
They are expensive and heavy, and available if anyone needs them.

As Ken B. just reported, I did have a torsion bar slip out of the pork chop
about 10 years ago. I, and friends, replaced the front frame clip.
Whoever among us who "checked" the installation of the right torsion bar
into the pork chop didn't do it properly -- as Ken said, the aft end of
the TB should have been flush with the aft side of the pork chop. Instead,
they were meshed by only 5/16"-3/8". On a bad bump in Texas, the front of
the coach dropped almost to the pavement and stayed there. I was lucky to
find a body shop a couple of miles down the road with room in their lot for
me to park. The owner helped me by providing a sheet of plywood to work on
and jack stands for safety. I jacked the front end up, unbolted the lower
ball joint, and lowered the A-arm. I had a little 3-ton jack from which I
removed the swivel pad on top of the plunger, leaving a round end to fit
into the pork
chop recess. I don't remember for sure, but I think I removed the dust
cap from the front of the A-arm socket to allow me to drive the TB back
into the pork chop. I never had any more trouble with it before installing
the 1-Ton front end 5-8 years later.

Thanks, Ken.
I don't see how adjusting the torsion bar up 10 turns could have made the bar more likely to fall out, unless the act of adjusting pushed it further into the control arm. In any event, the WSM specifies that the end of the torsion bar should be flush with the rear face of the porkchop.
Perhaps the inside of the torsion bar seat in the porkchop was damaged all along, and held when it was 10 turns looser but failed with the additional twist of 10 turns plus some driving.

At about 230000 miles on my 77, the rubber isolator (on the driver's side) that locates the torsion bar anchor crossmember, wore to the point that the crossmember worked itself aft enough for the torsion bar to come out of the porkchop. Driver's side came down with a big bang! I drove it home on the bump stop about 90 miles at a slow speed. Harvested an isolator out of a coach Manny was parting out, and all was well. Those rubber isolators are available now from Applied. I think the reason for the wear was that a hanger for a muffler had the crossmember in a side bind for about 100000 miles. Got the exhaust system hanging straight, and things still look good in that area. Next time you adjust ride height, it might be worth a look at those isolators.

This issue was based on a work that we did on a coach, When the coach came
in the complaint was about handling.
We checked it out first by checking air pressure, steering gear box
clocking and checking for excess slop of components.
The rear end was way off on one side, so we ded the Tricycle method to
level the rear then droppe the front and took measurements.
One side was approx. over one inch lower on side, while the other was close
to correct height.
My guys using the Tool to relieve the tension and made about 12 turns and
backing down the other side two turns.
We had the tension relieving tool on both side to save time.
Since we have a swivel pad , we had 3 guys bounce the front to help seek a
close height.
The customer took the coach and drove it .
At a parking lot the front made a bang noise and dropped down.
They brought it back and we say the the Pork chop had spun on the torsion
bar.
Looked like 1/4 " was what the torsion bar was in the pork chop.
In an ideal world, we should have checked the depth of torsion bar in the
pork chop.
We replaced the pork cop, n/c but charge one hour, as it took my tech took
3 hours as we had to reset the height.
So the issue is weather we should not have charged him for the work. I
contactee couple GMC shop and they felt it was not our fault .

I hate having a shop as we are always blamed for things .
If we did ALL the checking, then they will bitch.
I resent this as we only charged for 1/3 labor time and free pork chop.
Next time take it to another shop as I do not need this type of business.

What is the Tricycle method, Jim?
I have heard that you can support the rear with a point load support mid point between the bogies and then adjust the torsion bars with the front on the ground to level the coach side-to-side. A variation on supporting both bogies at ride height when adjusting the torsion bars.

I learned from Jim Bounds.
Lift the front at the beam in front with a bottle jack and the go to the
rear and have both sides at the same height.
Believe it or not the rear will maintain the level when you drop the frot
on the front wheels.
Naturally you want to lock the air at the bags.

By the way, there is so much tension created by the torsion bar, it is
impossible to slide it during the adjustment. If they think so they are
idiots ....

Quote:By the way, there is so much tension created by the torsion bar, it is
impossible to slide it during the adjustment
That makes sense to me - any additional twist would ADD friction. Any idea why it slipped out on the road? Bad porkchop to begin with, bad LCA bushings, or????

Jim, I did not get the impression that he was directly blaming your shop but rather he was asking if the the adjustment affected the torsion bar problem. I do not see how it could.
In my opinion one of two things caused it. Either someone previously installed it incorrectly (bar not inserted all the way in) or it slowly worked it's way forward over the years and miles. Neither one would have been your shop's fault. I can not imagine why anyone would or should have checked it over the years.
There is a hole in the back of the cross member where it could be checked.

So is this something we should all go out and check on our coaches? And how
would we specifically go about it?

I am still at Applied, who are helping me very good.
If you read back my post, I never, ever have blamed anyone ...
I just asked, as a non-technician how things work, are or aren't possible ....
Somehow Jim is interpreting it wrong.
But I will talk to him today, in person.
This is an disadvantage of communicating this way, ones somebody reads it wrongly, it gives wrong reactions on reactions .... etc.
I anyone who knows me by now, or should, knows I am a reasonable guy.
If I made a mistake or offended somebody, I say sorry ..
But still reading back my message .... I see only objective notes, a neutral question about those torsion bars, and even a remark how well they are taken care of us.
....... even helping us staying during the weekend on their "Applied RV Resort" ....
