No. I put used 70 series axles under it with unknown mileage. As far as I can recall, all I did was put new rotors and hub seals on it. Pretty sure all bearings remained stock. I replaced the TRE's when I did the swap back in 05.

Back in January, I replaced the trunions, TRE's, and tightened loads of stuff. Better, but still had the occasional "tire out of balance" feel on bumps right up until this trip. This trip was a nightmare on any uneven road surface, even dirt.

I rotated the tires and adjusted the toe out a little while out there. Helped but didn't fix it. On the way home, i noticed it pulls HARD to the right. Left springs are flat, so that kind of makes sense it would pull right. I need to pull a tape, but I'm guessing I have 1/2" more between axles on left than on the right.

Wow. Just noticing the time lapse in this thread.
I am interested because I have had some wobble issues w/ my 40.
I have tightened U-bolts, replaced U-bolt plates, added caster shims, replaced TREs, tightened shackle bolts and finally rotated tires and that seemed to help. I probably should replace bushings, have not done that in a while...

Yeah, I didn't get around to the major repairs on it until Christmas and hadn't seen the symptoms really come back until early this month.

I'll look for your updates.
I think Death Wobble would be a great dynamics class project for mechanical engineering students...

I think a trip to the alignment rack would be worth the money. You've been chasing something for a while now. A print out may display the smoking gun. Or at least point to the wheel in question.

If one side is sagging that bad it could be the problem. But has this always been the case or just recently?

Anyway I have OME springs on my 40 that worked very well. Well up until my engine fire anyway. I drove it daily for over a year on them. Speed tested to 100+. The front end has a SR as well. The truck was light. SBC, 2.5" OME with 33's. Stock front bumper, rear is custom by Cruiser Outfitters, no winch, did have a sub tank. Drove like a Caddy after the lift. Mine are older springs before they moved production. Maybe some things have changed?

Do you mean OME springs? Sorry, not familiar with your rig...

You'll have to ignore my ignorance. But what are these TRE's you guys keep talking about?

Tie Rod Ends (TRE)
I have replaced mine twice, but the first one's I think were shorted on grease. Doh.
Spring sag: I made this theory years ago and nobody on mud agreed with me that it would be substantial enough. I disagree. Jack up the rear frame so the rear axle droops all the way down. Measure the horizontal distance from the axle to the door. Now fully compress one side of the rear suspension (ramp) and measure again. You'll find the axle "moved" backwards a good bit. To me, it's not too far of a stretch to say that cruiser lean has an effect on alignment. My lean is now severe, last year was bad, and 3 years ago was almost non existent.

Thinking through your logic Barry, if lean contributed to alignment then with cruiser lean your rear axle would stick out towards the right as you drove down the highway, in a more crab-like stance. So you'd have to turn to the right just a little bit to compensate... have you notice you need to hold the wheel to the right a little more? Also how accurately could you measure wheelbase? If your theory holds it should be shorter on the DS.

i know it's a band-aid........ BUT


do you have a good steering stabilizer on there?

i went through everything on my rig including taking it to a place that measured the frame and verified it was good and nothing fixed it for me. I am talking every component was touched and replaced. axle housing is the only thing I didn't touch, but the frame shop said it was good.

A new steering stabilizer fixed it. band aid i know, but i was ready to sell the truck. My old one had a dead spot in it where it ran 99% of the time.
