After I go over a bump I notice the wheel shakes a little bit more then it should and a little longer then I should. Feels a bit loose or sloppy. Is this caused by bad steering rack bushes or something else? Also I notice the wheel alignment seems to have gone out a bit too easily/quickly. I have done the LCA bushes, change the LHS upper control arm and LHS hub and knuckle assembly, tie rod ends. I want a firmer and smoother ride.

scott, after turning a corner, if you let go of the steering wheel does the car self centre?


If not ball joint on LCA is stuffed.

Pretty sure it does self center I'll have to test it but I haven't noticed anything unusual like that.

Went for a drive and the steering wheel turns back almost all the way but not quite to center. Needs a slight correction or I'll drift across the lane. Seems about normal to me or should it come back 100%?

have a good look at the LCA ball joints. Check if there is any play in them. I had mine pull apart when driving, the not self centring was the warning symptom

What happens when they pull apart? Is the vehicle out of control? I'm not sure why but its pulling to the left but I swear it felt like it was pulling to the right yesterday. I changed the whole LHS control arm. The old one looked good before I destroyed it taking it off and the new worked decent. I'll check the right side when I get a chance.

i had both left and right pull apart. LHS at low speed on the road,(had to be trailered home) RHS pulling into my driveway.

to get them off you need a puller check "pitman arm puller" on ebay. Worth their weight in gold.

Did you just get replacements from rockauto? They are $66 each with the bush. Did you use Soarer or Supra ones?

i purchased second hand ones, repacked the ball joint and put new boot covers on with plenty of grease. The failed ones were pretty dry. Also replaced the bushes.

I think new ones would be the way to go now. I replaced mine probally 6-7 yrs ago.

I might look into that tool you mentioned. I bought one from an auto parts store and I bent it trying to get the ball joint off (took it back for a full refund). The fork type seem to be better.

I might give the aftermarket types a go. Are the supra ones suppose to be more beefy?

I was just driving and yes it pulls to the left a bit. Go over a speed hump or something and it will be pulling to the right instead. That is messed up. Something must be loose or shot for this to happen. The thing is everything looks pretty good visually last time it was checked.

I was wrong about the cause of my shifting alignment. It is to do with after I turn to the right it stays a bit off center to the right and left for a left turn. From my searching it is called memory steer. It says there are few causes such as-

"Worn and binding bearings in the strut towers will result in memory steer. It's also possible that the spring plate is worn, (also to) check bindings in front end linkage (sway bar links?) And bindings in ball joints." I'm guessing bindings means sieged?

scott, check the mounting bushes for the steering rack. get some one to move the steering wheel back and forth slowly and look under the car at the steering rack and the front wheels and see if thay are operating correctly. If the bushes are stuffed you will have movement of the steering wheel , the whole rack will move , but the front wheels will be delayed.

So the steering rack connect to the hub and knuckle assembly? So if I jack it up and turn the wheel and the tyres delay movement this would suggest lots of play and bad steering rack bushes? If the car is just on the ground would I also see this delayed movement?

Your steering rack bushes may not be as bad as they were on mine, but in my case there was excessive steering wheel play (and hence delayed steering response) even when parked. When driving and switching from left to right turn (or vise versa), it was very noticeable.

you may also wish to check that the wheel alignment nuts are on sufficiently tight; I had one that was loose after a a dodgy wheel alignment, and consequently things would move around, especially on bumps or when braking.

check it on the ground. there are 2 bolts and bushes together that hold the steering rack in place. the 2 bushes chew out. the car wanders.

If I turn the wheel very slowly the wheel doesn't move for a couple of seconds before it starts to 'hook up'. If I stop and continue the same way if turns instantly but if I turn the opposite way it has that second delay before it starts to turn. Steering rod bushings? Rough location? Will get under and have a look.

the 2 are together and easy to see. the 2nd one is in behind the 1st one. you need to loosen a 3rd mount over on the lhs to replace them. I purchased rubber ones from peter taplin.

I order some 50mm sized bushes. Its pretty easy to do from what I've been reading though one is hard to get to supposedly. By the sounds of it an hour is enough time to get the job done.

Should only take 1 hour to change them , except if it a 32 , the top 50mm bush is very hard to get to the nut on top is tricky as well, I found on the 32's you can undo all the bushes, jack up the engine after undoing the engine mounts and removing air intake rubber bellow, slide the rack a little toward the drivers side and turn it 15 deg or so, this does allow you to get quite good access to the top 50mm bush.

On a 31 though there is nothing I need to undo to get to it? Want to avoid jacking up engine etc.

I used to do them under the car , but found it easyer to remove the alternator to get to them.

I will try without removing alternator but definitely want to learn how to change alternator and P/S pump as they are the Achilles heel of the 1uz. I did the first one today. The big bush. Was a piece of cake. Original one didn't look to bad so hope this is actually the cause of my issue. Two more to do tomorrow.

the big circular bush on the LHS will not be the problem. You need to remove it to get rack movement to replace the other 2 .
