I'm Back! '90 GTUs

It was originally on the back and made a low, rumbling sound between 45-70 mph. It wasn't until I rotated the wheels and it was on the front that it was really noticeable, but again only from 45-70 mph.

Well at first it was just I noticed that it was happening during driving. But It was also happening during free revving too. But I replaced the driveshaft after Adler looked and said the joints in my old one were basically falling apart. I want to say that the vibration has lessened since replacing the ds but its kinda hard to say.

It doesnt really get worse or better with RPM increase. But I have noticed that in 3rd gear between 3-4k it seems heavier (I know that this isnt helpful haha).

What has changed since driving the car home? Are the wheels the same ones on the car? Did it not do this on that trip?

Yes the wheels are the same and it did do this on the road trip. It SEEMS to have smoothed out some since the driveshaft swap. I was trying to rule things out so the trans mounts and motor mounts have also been replaced.

Well, my guess is wheels. . If we're still on for this Fri. and you haven't picked up your wheels from Charles yet, I can bring my 7 so we can swap my wheels onto yours for testing. Let me know so I can drive it. . Actually, what I may do is remove them at home and bring them in the car but again, let me know.

The wheels would be a good guess. They are terrible.....

Zach has a good plan, but you need to get your old ones from Charles!!

Yes I do. I'll try and remember to get them as soon as I can. I might be able to swing by there this evening and get them. Not sure yet. They need a good cleaning after sitting over there for so long.

Yeah, I'll be going out of town Saturday. We can another weekend if Friday won't work.

We might need to wait. I'll just try and get my wheels from Charles. I have a big photo job that needs to be done by Friday so I'm gonna be pretty busy with that.

Also I should add.... that this vibration happens even when sitting still when i rev the car. It did that even before the driveshaft replacement.

[FC Zach]

If that's the case then there was no reason to replace the driveshaft. . Probably something off on the engine, possibly a defective clutch or flywheel.

Thats what I was saying originally but when Adler looked at the shaft on the lift said the the joint were definitely bad. So I figured it couldn't hurt.

Is the best/only way to confirm the clutch or flywheel being screwed to take the trans off?

[FC Zach]

I think so.
