It's spring in N.H. and the roads are rough and either my memory is bad or my Tr4 front end continues to shake around way more for quite a while after a sharp bump. It feels in the steering wheel like it vibrates horizontally not up and down. Here's what I have done so far with little effect.
Rebuild the rack and pinion and interior ball joints. It is shimmed so there there is no slack but moves freely. I reinstalled the whole rack assembly by the book, even made a spreader to push the rubber bushings tight to to rack flanges. I adjusted the toe in by the book after installing the rack.
There does not seem to be any slop in the out board ball joints when the weight is on the wheels and the steering wheel is moved back and forth.
The front suspension has about 4,000 miles on a rebuild and it just seems bad recently. I lubricate about every 1,000 miles
I just installed new Koni adjustable shocks with only slight improvement. Tires are inflated to spec and well balanced with no shake at all on smooth road up to 80mph.
The shaking is there whether on the straight or in a tight corner in either direction. Usually under 80mph. Actully it seems that the faster I go the less it vibrates after a sharp bump. Probably the gyro effect.
I sure would appreciate any suggestions.
Thanks, Phil
