Awesome. Do you have a GS? or IS250awd?

Also, did you install on all 4 axles and how does it stay in place? is it bolted down? or just slide between the axle and transmission? i never looked thoroughly.

Thanks

ah... just re-read the description. So they just slide on. is the inner diameter the same as well? in other words, when you're trying to hold them in place and bolting the axle nut down, they aren't gonna be moving up and down correct?

it still vibrates and woubles. i did not see any improvment.
i have glued them centered.
after couble of miles, i got Check VSC, must be the speed sensor, very expensive fix..

good lord!!!!

Mine seems to be intermittent. Sometimes it's smooth sometimes its not. I wonder if its the U joint on the driveshaft...

I wonder if it's possible to put the car on an awd dyno machine. get behind the car and have the tuner or someone drive the car on the rollers to mimic the problem and see if there is anything wobbling.

On the s2000's the axles weren't the portion that wobbles, it would be the cv cup where the 3 rollers would lay inside, make a certain groove or pit so when it was lowered the rollers inside the cup would now be pulled out slightly and just kinda roll on the edge of the pits or grooves and thus causing the wobbling/vibration feeling. But that's what the half shaft spacers would do is push the axle back together allowing it to be back in its original place.

Doesn't appear to be the same on the IS.

How expensive are the axles?

the spacers for the wobbles..they go on the front axles or the rear ones?... and one more thing ..if i remember the rear driveshaft the one leaving from the transfer case to differantial.. would the car still drive ,.just to do my own test ..cause i feel like its coming from the rear..

That was the question i had, because this is my thought.

The spacers, should most likely go on ALL 4 axles. not just the fronts.

I would WANT to believe if you disconnected the propeller shaft to the rear differential, the front wheel drive would kick in. I believe that's what it's supposed to do anyways on these cars considering these cars aren't a true awd car. They are rear wheel drive until the rear wheels slips, then the front wheels kick in and making the car awd.

I'm curious as to your issue may be the U joint in the propeller shaft. or guibo. Which is the flex coupling.

I'm hoping i have that same issue as i was having some vibrations sometimes even before i lowered the car..

you didnt center them unfortunately or else you would not of had those lights

please keep in mind, i never said this fixes the problem 100%. from the time i had these installed, it drastically decreased the vibration/wobble i had. this has always been the case since the day i had them installed, which you can read my post here or here

Do you possibly think the rears could benefit from these as well? I've noticed it was just for the fronts.

no, it is just the fronts. the problem is exactly how you described it and it has all been covered in the awd suspension thread.

when the car is on a lift you can clearly see the axles are at an awkward angle. the spacers just help push the axles back towards the center of the car to help straighten everything out.
