Is there any problem on this, ie: does it make the torque box bind??
Also, how/what did you do/use for the jacking system that I see
atached on the bogie frame?
Thankx

Charles,
The massive bearing mount Rick designed that is bolted to the inboard
side of the suspension arm and the harden steel bearing is probably
10 times stronger then the bearing I used on my original concept
which I had no problems with several years of driving. I don't think
there is any concern with the torque box twisting. The true track
bearing is only putting a horizontal in and out load on the torque
box I don't know if you noticed the angle-iron bracket has three
different mounting holes for the bearing which is mounted in the
center hole. My intension is to some day mount two true track
bearings,one in the top hole and one in the bottom hole to see if it
helps reduce the suspension arm twisting and maybe reduce some of the
inherent mid axle steering. I get all of my GMC parts free from Jim
so if I break something he will replace it.
As for the 12v dc stabilizer jack you saw in the photo, they are
probably the most useful modification I have made to our GMC. I have
two in the rear and two in the front that have been on our current
GMC for over 20 years and I had the same units on a previous GMC for
5 years. They are RV trailer tong jacks that I got from Camping
World back in 1985 that I modified slightly for mounting on the GMC.
They are rated for 3,000 pounds and have a slip clutch that prevents
any chance of overloading. Manny is the only person I know of that
has copied the concept. There are 4 DPDT switches on my dash for
control. When I go to a campground I level my coach using the air
bags like most of you folks and then put down the jacks and vent the
air bags down and you can't see any rocking of our coach based on
internal activities (don't I wish). The front jacks will lift the
front off the ground but the slip clutch will will prevent lifting
the rear totally of the ground. I have been in only one camp ground
where I could not lift the rear high enough to get it level.
However, they will hold the total weight of the rear.
I use the one on the left rear to do double duty. When I am driving,
I use it to actuate the parking brake (shown on my "chuckieboy" photo
site) to lock the two left rear wheels together. The jack has enough
capability to hold the coach position with the air bag vented. You
don't want to know how I know that. When at a camp site I disengage
a locking lug and it them becomes a stabilizer jack. I store out GMC
in an inclosed area between the garage and a high block wall on the
left side. I have a garage side door that allows entry while parked
but I do not have enough room to access the left and right side of
the MH. When I park it I lower the two rear jacks and vent off the
air bags. When I get ready to move it, I hook my garage air system
to a QD under the front hood and air-up the coach air system.
If anyone has any questions about anything GMC please feel free to
contact me by email or phone.
Chuck who has to much crap on his GMC
