Rear axle off center 77 FJ40 (1 Viewer)

[myquestoyota]

I was looking at the outside wall behind my driver side rear tire and saw scuff marks. I got to measuring and found out my passenger tire is an inch and a half farther out than my driver's side. I see no obvious reason why this is. OME springs and shackles. I'll get some pictures.

Interesting...could be axle-to-frame, or frame-to-body I suppose.

Should be able to measure tire-to-frame on both sides and get a clear answer...would wager it's the axle, but in theory it could also be worn body mounts.

homemade shackles?
worn spring bushings?
jack it up by the frame and see if it returns to center?

Cruiser lean to the driver side all the time , this make it look worst

Looks like a body lean not suspension which is even worse. Compare the rear frame to the sill.

Different offset wheels?

I measured from the body and from the frame and really didn't see the anything but that it is off. Original frame and body. I did install the OME springs and new OME shackles and bushings about 8 years ago. It's probably not a new thing but want to correct it.

Hey myquestoyota! Was walking around my ‘82 43, yesterday, and noticed the same thing…right rear wheel stands visibly farther out from body panel than left one…haven’t measured, yet, but looks like 1.5 to 2 inches. Did you ever diagnose a single cause for this?
Mine is only an occasional driver, but roads here are potholed and washboarded, so wonder — without yet exploring under my rig — whether the axle has “slipped” to the right due to some big knock.
Appreciate any observations you‘d like to share! Thanks!

- This here is EAZY PEEZY cause here to diagnose :

- one or both leaf spring center / centering pins is missing or the cylinder shaped TOP head is gone fore some unknown reason like rust or snapped off maybe too here

from age time or hard - core off road wodner-tainment by the PO ........


- lastly , same center pin topic here :

- LOOSE U-BOLTS maybe caused the AXLE to HOP over the center pin or simply CHOP IT'S HEAD OFF ......

I agree, jack it up until rear is hanging, see if it moves back, if not push it back while jacked up by frame , no weight on tires, when pushing back see what moves, may just be bushings need replacement, while jacked up also check u bolts, wouldnt hurt to lossen them and check center pins as well.

43? Is it from South America?

Axle perched probably broke off and were welded on wrong, seen that quite a few times, along with bent/broken spring hangers re welded on in the wrong place, missing spring center pins, hombrew shackles, etc

I've seen that in the past on various full framed vehicles and a diagonal measurement of the frame indicated that it was off square. Does it dog leg? That can cause the tire scuffing.

Probably twisted frame. The later years had scaled down frames.

I spent some time underneath it replacing body mounts and noticed that the springs tended to have some bias toward one side. I think that if I loosen the u bolts and suspend the axle I may be able to center it some.

 

[peesalot]

replace the bushings when you do that, loose shackle will let the axle shift left & right as well. You havent jacked it up yet ?

The springs and perches are supposed to be pinned, so you shouldn't be able make adjustments like this.

 

[peesalot]

Unless your center pins are broken, or u bolts loose, the only other movement is in the shackles and bushings. just outa curiosity have you checked he back space on the rims ?

Brand new oem rims, the OME shackles, springs and bushings have been on for 10 years. No rock climbing
