Check the subframe mounts for ripped or missing rubber the front diff mounts as well as the sway bar mounts.

Then check and see if you have axel hub play. GL

The phone works.
LOL

 

I believe our last conversation that the prices have indeed went through the roof for these things, especially for Jays 6 speed.

 

Will do, aint it past your bedtime?????

Make it go ring.

 

Sorry I was unaware of that. I didn't mean to mislead you OP.

 

sc400 gear needs to be 97+ since it runs a 5 speed auto. A 98-00 gs400 also has a 5 speed auto.

GS400 is also a 3.266

I found this on supra forums. I would try to stay 3.76 and below.

97-00 SC400 3.266

92-97 SC300

Jwin thanks for the details for all the related models. I am on the hunt for a TT auto at 3.76 ratio. I would like this to be plug and play as much as possible. I do indeed have the stock SC400 rearend in it now. I clocked it on high boost (21 psi) a few months ago and could go 111mph in 3rd just before 4th, if this matters. I am sure with this ratio it would be a slight difference, of how much I dont know. I even tossed the idea around of selling these wheels and going with something heavier and wider. Was thinking this would cure my problem but after going with a wider tire this eliminated my theory as soon as they were mounted.

 

I have the auto tt lsd 3.76 in my car with a r154. I like it. Highway cruising is nice since its about 2500 at 65 mph roughly I can't remember. a GS400 or 97+ SC400 rear end isn't bad either but I would only use it for the gearing and throw in a LSD either torsen or TRD. I am currently trying to find a 3.24 gear right now to put into my auto TT diff. I like low rpm highway cruising and it could help save my transmission as well with the lower gear.

 

I have around 430whp on an open diff and I do not have this problem.

 

GS400 has the tallest ratio 3.26 at least the one I grabbed did.. not to sure if there are other rear ends offered for the gs400

 

could this be from a bad wheel bearing? NO one seemed to mention that???

 

I mentioned it above.
Shouldn't you still be sleeping its only 9am

 

Crack a Pow..... You did mention that... I reread it again. I am still asleep. Some of us have four days a week off.

 

That's because you have have some good tires

 

check your rear control arm bushings. If ever when you pull the ebrake and it makes a slight "clunk" sound, you rear uppers may have too much movement and this can make the rear end "squirly". It's worth a quick check.
