MR2 SW20 Steering Wheel Wont Return

[garthalgar]

Just bought a 1992 MR2 SW20 (non power steering model) and drove it back from edinburgh. It had quite tremendous steering wheel wobble, which I knew before I bought it and still put it down to the front wheels being improperly balanced. After all it does have Wang Li Ching Ho tyres.

BUT! My main problem is that when taking a slow turn to the right, and letting the steering wheel return to its natural position, it ends up slightly off kilter to the right and the car will pull in the direction. The same problem happens when I make a left turn, but the wheel will finish slightly off kilter to the left and pull in that direction. After a while of driving straight it and I let go of the wheel itll be back in the middle again and not pull either way. 

I'm stuck for ideas here now. Alignment is probably off but I reckon its worn bushes somewhere allowing play in the steering. Dad thinks its that the adjustment for the steering column is too tight so isnt "loose" enough to go all the way back straight.

Maybe its something silly, but as long as its something I can do myself i'll be chuffed Might need a replacement column or rack?

Have a look?
the column adjuster wouldn't lock the steering, it acts on the outer column that does not turn, probably trcking but it could be excessive castor, could be a seized UJ in the column, could be a lot of things TBH.

Lack of castor will cause the steering not to return, it can also cause steering wobble, as Rob says it could be something seized, Jack it up and see if the steering frees off, (both wheels off the ground,)

Agreed with V8ian. Hopefully it's just something seized, or huge slop in the bottom joints. Jack up the front and spin the steering from side to side to make sure it turns freely : do the same with another car for comparison if you need to.
The only other thing I can think of from what you describe is lack of castor, as V8ian says. To have that on both sides, worst case, maybe suspension misalignment? I can only imagine a PO driving squarely and at speed onto a high kerb to push the suspension back to cause that to happen evenly on both sides. Possible, but very unlikely.
