got a 88 rx7 gxl not long ago(week or two), and when i hit over 30mph the whole car shakes, when i throw it into nuetral it goes away when im below 40-45, when im over that it keeps shaking, im doubting its wheel balance because it wouldnt stop. i was checking mazdatrix and juding from the symptoms it seems like the rear u-joint is going bad, anyone else ever have this problem? above 60, it seems to get weaker.

quick question, it also seems the throw out bearing is going bad since when im sitting in a parking lot doing nothing, it doesnt sound like something grinding, just like there's something worn lose, would that be the throw out bearing as well?

edit: im going off of this

u joints. happened to my stang.

 

cool, i'll order the driveshaft from mazdatrix if nobody knows a better place.

edit: im gonna get the 86-88 n/t manual transmission aftermarket driveshaft.

i also wanted to ask, the headlight on the driver side doesnt go down, he said he disconnected it because it just didnt work, where would i be able to get the parts to fix this, i've heard of it going bad kinda often but not all the time.

Your tires may be worn beyond usefullness. Check to see if the belts are separated.

 

Did you even read his post? If it was his tires, it wouldn't matter if he was in neutral or not.

 

well considering that i can get all the tools and then some(just not rotary engine specific type) i think im gonna go with just replacing the u joints.

 

Do you have any clue what you are talking about? Maybe you should read it again.

Besides... YOU ARE DEAD WRONG, separated belts can smooth out under certain speeds and then reveal themselves again at higher speeds.

 

My apologies.. Its your tires dude.

On a 19 year old car, I would guess the factory u-joints would be the culprit over something that is regularly replaced.

But apparently I don't know what I'm talking about.. so don't listen to what I'm saying.

 

yeah but i hear a clunk when i let off the accelerator.

 

Dude.. sounds like your u-joints for sure. Ignore BLKTOPTRVL.

Could also be your rear diff mounts or something.. but most likely its your u-joints.

 

i wish it was the tires, that would be really easy to replace.....

 

No, you're not wrong because you made a suggestion. You may be right about the shaft. But I may be right too.

Where you are wrong is that you offer a smart-*** response to a reasonable suggestion that I made to try to help the guy out. That's what you should apologise for, instead of backing out of your statement/accusation.

 

Geeze man. Calm down... sheesh.

 

Stop making smart-*** remarks - especially when you are wrong - and nobody will have to calm down.

 

Okay.. for the record, I apologize for not taking life to seriously and making jokes. I'm REALLY sorry if I have offended anyone. If I have offended you, let me know and I'll type up a full apology in letterhead and send it to you priority mail.

 

Send it today - Rush. And maybe I will forgive you.

 

simma down nah...

 

Great SnL skit.

 

if you are positive that it is you driveshaft or u joints, just go out to a driveline shop and see what they will charge you to fix or replace it. if you cant find a drivline shop, ask a trucker! they will know.

 

I tried that actually, but because its a "non-rebuildable" driveshaft, most of them won't touch it.

If it WAS rebuildable, we wouldn't be having this conversation. U-Joints are too damn easy to replace for there to even be a write-up. LOL.

Go pull your driveshaft off (mark where it comes off though so you can bolt it back up to the diff in the EXACT same way). After you have it off, follow the writeup on my site. Its REALLY easy to get them out. Ask anybody who's been in the 4x4 scene before.

 

what im going to do, is try to find a junkyard where the guy said he knows of lots of parts cars, and see if i cant pull a driveshaft from a car like mine. he's already pulled lots of other little things for it, i figured they probly have at least one spair sitting over there as well.
