92 sc400 lowered on Tanabe. New Rack and Pinion Bushings,inner and outter tierod ends. When i driving if i hit a bump or any uneven in the road the car pulls VERY had to the left or the right and i have to be counter steering like a mf. Its driving me crazy i went under ther yesterday and everything feels solid and looks ok to me. also wen i hit a bump in the road there is a thumping sound from under the cars. ANY IDEAS?

You need an alignment sir.

LCA's, check your bushings.

New Monroe Shocks,no alignment yet but i dnt think that would cause a thumping noise.

Thumping = Something Loose

Did you torque everything to spec that you touched?

bump steer?

not to specs but they are pretty tight.

I would definitely take off your wheels and re-torque everything. Also check your control arm bushings while you're down there. Also, get an alignment.

You need to go back and retorque to spec - when you're touching things you can't recreate the weight this car puts on the suspension components.

Future reference, anything you touch - retorque it to spec.

That "bumpsteer" i had the same issues on my car 2 year ago, i was talking to my buddy about that last month because he had the same issue, but did the alignment that fixed it a little but still has the problem.
He is on tanabe and kyb'S.

Bump Steer usually only becomes a real big problem whenever you change the suspension geometry outside of it's stable range.

I hate looking at my tie rods and seeing them angled the way they are.

thanks guys......im going to get some wheels and them get an alignment.

Very critical step that is often overlooked and if you have uneven tire wear then this will cause the problem with the twitching you described and will also not offer an accurate alignment reading so tires are also critical now this assumes all bushings are up to par.

I had the same issue, I replace the front bushings with poly ones and the car was left to right and the steering felt really soft, after proper alignment car drives straight also I am on megan coil overs.
