rear axel shifting after turning coners

vvack0matic · Jun 19, 2006

this may sound a bit strange but i have no clue where to start to look,
heres the prob.

the truck is a 92 f-150 4x4
whats happening is when the steering wheel is cranked to the left to drive around a coner, when the wheel is brought back center, the rear wheels are off just a tad and keep going in the direction of the last coner, the offset of the rear wheels is not much but what the hecks happening

same as when the steering wheel is brought to the right to drive round a coner the rear wheels shift and continue the right coner when the wheel is brought straight, it sounds bad but the offset of the rear wheels is about a inch in both directions

i looked at the rear wheel axle bolts (the clamps that bolt the axle to the frame) and every thing is solid, only thing i see is the rear shocks are rusted out bad, can a rusted out shock do this or is there something else going on here.

i asked the owner when did this start happing seeing not more than a month before i was driving it and it was fine, they said after hitting pot holes the rear axle started to shift but it wasnt much at all (prob, bout 1/8", after being drove and hitting more pot holes the axle sifting when turning round coners became more noticeable.

i have no idea whats going on, help on this one would go a long way.

just to keep you all informed, heres just where the truck is at now, posting the problem throughout post boards on the net

i was under it today looking at the leaf springs
it all looked solid, i was thinking perhaps a mount to one, or the bushings was busted,but seeing where they tie in everything is ok, and still nothing

how are axle`s (rear wheel drive) put together is there a bearing on the outter edge of the axle, but still within it holding the shaft between both ends, i can see if one of them where shot or rotted out on one side it could make for the problem, but i dont know how an axle is put together,
to explain it better,
( after the truck takes the turn the rear end shifts a inch in the direction and will stay at that offset while trying to drive down the road straight, the front wheels need ot be counter steered a inch to correct the offset of the rear wheels, when the truck is stoped you can see the body of the truck offset from the rear wheels from the last coner,
what-ever the last coner was left or right both rear wheels stay in that direction, offset a inch from straight,
how are rear wheel axle built and whats in it that could go wrong to cause this, i have not jacked up the truck to see if the rear wheels are just sloping around within the axle,
2morrow i`ll find a way to get the rear in the air
