Very interesting.

This issue is also starting to affect my 2003 430 with 95k on it. I need new rear pads, so my plan is to replace rears with oem or ceramic pads, fit the oem shim kit, check the rotor for movement, then if the problem is still there I'll move onto the rear upper arms.

This is def. Something I would check, good call on that. Btw, haha what I'm experiencing is exactly that your describing as well believe me, almost feels as if it's torquey, and in a sense I could def. Imagine weak brakes aiding to that. But if your tranny mounts weren't bad, then lol, why'd you even change them, 2gs's motor and tranny mounts are known to go, are you assuming they were good because you didn't swap them and they told you this? Well anyhow I'm going to be installing my whole big brake kit probably this weekend, (as long as my rotors come in) and while I've got the car up there I'm going to take a feel for the RUCA's as well, if the issue goes away after the brake system install, then great! We know, and I'll report back about how my arms feel as well, as I'm 100% sure they have to be shot... That's prob the issue good call ^ thanks

Agree..... The more I ponder about this it also makes me question if the clunk, which doesn't even happen everytime Btw, but it's hard to imagine that the bushings would be so worn that it would cause metal to metal contact, to me it seems like there must be some play else where as well to cause that kind of torque to cause (if it is the bushings) the have metal to metal. Btw OP, tranny mounts, motor mounts, don't have to be no longer "intact" for a lack of a better term, in order to exhibit the indicators of them being "bad" and also, your Trans sends torque to your drive shaft that's connected to your differential, which also distribute force to your axles.... I hope for the best for you buddy, I just don't have the most faith in these trannys, they all do the same s*** and it's aggravating as hell. Just take a pry bar and feel for play when you take your brakes apart or what not... Actually take it to everything lol, I will too... Hope nothings loose...

Go on youtube type gs300 rear carrier bushing play)

I just had my brakes checked and while they did say that I had an issue with my front rotors and pads, I believe it is unrelated. The rear brakes were fine.

The last time I had it into my mechanic he said the rear driveline bushing is bad and that I would have to replace the whole drive shaft because lexus doesn't just sell the bushing... I tried asking if it was the rear axle carrier bushings and he said no. I also asked if it was the drive shaft carrier bushing and he said no.

Does anyone know if this bushing is related to my issue and what the heck he is talking about?

joeyfett

I'm having the same issue but with a creaky sound involved

Behemoth7

Wrong thread dude

Behemoth7

Any luck with the brake install? Did it fix the problem your experiencing and did you find any play in the suspension?

GSGenesis

Nope. I'm starting to think that I may have over exagerated my sense of how my car was shifting, do me a favor, with it as quite as you can get, get a video clip of yours doing it could you? Post it up onto youtube and paste the link I want to hear it and see it first hand. Try with the phoneinside the car with you, then also set the phone out side of your car beside the driver door speaker facing the Trans, shift again, then record it one more time with the phone under your diff if you would, let's hear this....

Suspension(you can actually see ride height go up and down as I shift):

Driveshaft/differential:

Transmission:

Based on this, I have to believe that it has something to do with the suspension... Do you agree?

Behemoth7

I posted the vids, forgot to quote you.

nvsaccord

I have the same issue with the clunking when putting it into drive and reverse.

GSGenesis

NICE BRO!!!! Awesome, let me take a look at these hang on.

GSGenesis

Man, honestly I don't see this having anything to do with suspension...first off you said you changed your Trans mounts right? AND motor mounts? IF SO. Then by the looks and the sounds man. I'm drifting towards it being possibly your U-Joints man considering it's noisy only when switching into the two gears that cause the apposing contacts to mate, when there usually is no slack in that engagement the contact will not exhibit such a clunking noise, but if they are bad, the clunk can easily be the make up of room once contact is made. I know at least in the 4x4 world that's dam common if you don't have good U joints, I'm not sure if it's a common issue with these cars, but you can try and check! The easiest way to do it would be have someone else shift it from drive to neutral then reverse a couple times while you watch the drivetrain underneath from the side. Make sure the parking brake is set, the wheels chocked, and that the person keeps the brakes depressed. Watch for the make up of play sometimes you can even feel it, but it's really best to get the rear of the car off the ground, to get all tension off the driveline, and check for play with a monkey bar at the least, but being able to remove them and check though is ideal. Could even be your axel bearings man. I'll tell you what, you just gave me another job to do. I'm switching these from a GS that I'm parting that's newer than the GS I have that does this, dam you..... I'll let you know what I may encounter. Going to be at least a week id say though k. Maybe this weekend. God dangit...
