I struggled for an accurate title for this thread and this was it. So for the the last 3 years I've been driving this M1008 around. I picked it up on my way to the 2009 GA Rally. When I first drove it out on Randolph Church Rd I noticed it would wiggle when you wicked the throttle and wiggle when you let off. Changing tire pressure had an effect on it but never really fixed the problem. Despite countless inspections, I was never able to find the problem. Fast forward to last week, I was again trying to find the problem thinking it was bad spring bushings or center pins in the springs. While looking up inside the spring perch II couldn't see the pin in the hole and thought I found my problem.
Yesterday I set off to replace the center pins. Much to my surprise I found them intact. I did find 2 other things.
While wrenching the U-Bolts off I was supporting myself on the brake drum when I noticed lateral movement. Actually it was quite a bit of movement. Startled I went and checked the other side and it too, had a substantial amount of lateral movement.
By design, the rear U-Bolts are subject to heavy rusting as the spring plates capture sand, dirt and subsequently water. More on this later.
So I pulled the axle shafts to inspect. No odd wear or anything like that, it just appears that whomever was in there last time, didn't preload the bearings. I pulled the square key out and adjusted them up on both sides and took it for a spin. Tail wag is all gone now. Bad on my behalf as the inspection ports showed good shoes and no seal leaks so I never opened it up. I'll do better maintenance from now on. Here's a pic of the corroded U-Bolts. Anyone with the M1008, 1028, 1010 and 1031 should consider replacing or checking these U-Bolts
