lol. the only way to get rid of it to this point is to raise the car back up. but who wants to do that??
though, the new youzealand kit may help....

 

i have a gs300 awd and i can feel a vibration at low speeds ,however i am intersted in seling the car. it is a 2006 wuth 58000 miles i have tanable exhaust, f-sport front and rear sway bars, asa 20x8 wheels in the front and 20x9 in the rear.....and it is lowered .8 inches in the front and .6 in the front no accidents second owner ... it has navigation ,park assist front and rear and also mark levinson im looking to get 23995 for it stock or 24995 with all the adds

 

When lowering your car you alter the driveshaft angle which causes driveline vibration because it forces the driveshaft angle to be different with the transmission angle causing vibration.
There is 3 ways you could solve the problem. Either shorten the length of your driveshaft, alter your Slip yoke which also changes your length and angle of your driveshaft or changing your transmission mounts so that you can lower or raise the angle to match your driveshaft angle. These 3 ways will cancel or reduce vibration by alot.

hope this helps.

187 - i will ask my mechanic about the slip yolk adjustment when i see him next week. let you know if anything helpfull arises.

thanks again ING.

 

yea i heard about the slip yolk before but im still not sold that it would solve the problem. im interested in what your mechanic has to say.

 

No problem, anything to help CL community. =)

 

I dunno, maybe I'm not understanding the dynamics of this car completely, but anything that has to do with the rear driveshaft/slip yolk doesn't seem like it would cause the vibrations/wobble. I think it is the front driveshafts (axels) is whats causing this (maybe thats exactly what you said above). Which really baffles me, because in the past I've dumped some front wheel drive cars with no ill effects like this. I mean, 6+ inches lower than stock, and nothing but camber wear.

 

The slip yoke is splined to the external splines of the transmission outputshaft. When going over bumps the rear axle is moving up and down on the suspension system. In so doing the distance between the transmission and the rear axle is continually changing. The slipyoke will move in and out on the transmission shaft to compensate for this change of distance. The spline of the slip yoke fits snugly to the spline of the transmission output shaft and is free to move in and out as necessary.

its not the rear axle its the fronts that cause the problem and the cars are awd not fwd

 

Yeah, I get that. But I've lowered cars a lot lower than my AWD with no ill effects. I guess these cars weren't designed to be lowered.

 

your talking about fwd vs awd though

 

Yes, but its really only the fwd portion that's being affected. This topic is like beating a dead horse... Maybe those sage RCA thingies might help...

 

fwd and awd are 2 totally different things. thats like comparing apples to oranges.

 

i was not able to get to the mechanincs this week. i will try next week. i asked a lexus tech at a meet over the weekend, and he did not know anything about it. he is looking into though.
ING - can you provide any more info, such as where to look for this so we can adjust? i imagine it is somewhere on the front end....

 

ryan, this may help
