Good afternoon,
I did my front wheel bearings about a year ago with new set 23's and seals, drilled for fittings ,and have been just checking for looseness anytime they where in the air. When I did the rebuild,the PO's widow gave me a bunch of parts with, what I thought was rebuilt knuckles and they measured right on specs. Have noticed the right is a little looser than the left when rocking top to bottom. About as loose as the standard type wheel bearings on the rears. The left has a little looseness but not near as discernable. Even did a temp check when we got back from a 100 mile run. My VOM has a temp probe and I held it on the right and got 114-115F and the left was 116-117F with it being 95F outside. Always been able to hold my hand on all the bearings, they are warm as you'd expect but no real discomfort to touch. Before someone asked, I just did the upper and lower ball joints and this extra looseness was there before I changed the balljoints. Just trying to determine if the temps and looseness sounds in line or do I need to check, I have a spare bearing set if I need to, and if I need a hub I'll cross that when I come to it. Also is there any CV boots out there other than Dormans. Mine seem to dry rot within 6 months. In the spare parts I got there were some that are of a harder rubber and real shiny, anyone familiar with these. As usual if you or any of your IM force, oops sorry having a 60's flashback, what I meant to say was as usual any comments or opinion are greatly appreciated. We may not always agree but this is still America where we have the right to disagree contrary to public opinion that that is not PC. But I have never been accused of being politically correct. Off my soapbox for now.

Good afternoon,
I did my front wheel bearings about a year ago with new set 23's and seals, drilled for fittings ,and have been just checking for
looseness anytime they where in the air. When I did the rebuild,the PO's widow gave me a bunch of parts with, what I thought was
rebuilt knuckles and they measured right on specs.
I ASSUME YOU MEASURED THE ID OF THE BEARING BORES?
Have noticed the right is a little looser than the left when rocking top to bottom. About as loose as the standard type wheel
bearings
on the rears. The left has a little looseness but not near as discernable.
I WOULD SUGGEST YOU PUT YOUR FRONT END UP ON BLOCK, REMOVE THE WHEELS, ATTACH A DIAL INDICATOR TO THE SUSPENSION AND TOUCH THE DISK
AT 12:00 WITH THE TIP AND MEASURE THE PLAY IN AND OUT ON BOTH WHEELS.
Even did a temp check when we got back from a 100 mile run. My VOM has a temp probe and I held it on the right and got 114-115F and
the left was 116-117F with it being 95F outside. Always been able to hold my hand on all the bearings, they are warm as you'd expect
but no real discomfort to touch. Before someone asked, I just did the upper and lower ball joints and this extra looseness was there
before I changed the balljoints. Just trying to determine if the temps and looseness sounds in line or do I need to check, I
have a spare bearing set if I need to, and if I need a hub I'll cross that when I come to it.
I RECKON IF YOU DO THE ABOVE CHECK WE COULD MAKE A BETTER ASSESSMENT. IIRC JIMK CHECKS THE HUB / KNUCKLE ASSEMBLY AFTER THEY ARE
ASSEMBLED AT HIS SHOP.
Also is there any CV boots out there other than Dormans.
Mine seem to dry rot within 6 months. In the spare parts I got there were some that are of a harder rubber and real shiny, anyone
familiar with these.
WHAT COLOR ARE THEY? IF THEY ARE BLUE YOU GOT LUCKY THEY ARE INDESTRUCTIBLE!
As usual if you or any of your IM force, oops sorry having a 60's flashback, what I meant to say was as usual any comments or
opinion are greatly appreciated. We may not always agree but this is still America where we have the right to disagree contrary to

Can do the disc rock and check the e play. Are there any specs on how much is allowed since the play is multiplied because of the width of the disc . The boots I have are black . We're the blue the ones I 've heard called super boots and are they still available ?

This is what I use for a baseline and change check. Dail indicator on the outside of the rim to the ground, wheel in the air. Tip the wheel in and out. Everything moves so its kind of a guess what it really measures but I'm getting around .020" Previous we had one side that went from .040 to .080 over time. A reman hub and bearing got it back. Maybe this won't tell if your headed for a catastrophic failure but at least you know if something is changing.
