ok its an auto. i just put new tires on it and that helped a little. when im at about 5000+ it vibrates like crazy and makes the cd player skip. i know my u joints are going out and i was thinking these were related but now that i think about it it seems less like that would be thed cause. its not so much of a speed problem but an rpm prob. when im going 70 in fourth and get on it and it goes to 3rd it vibrates a whoooole lot. any ideas??

the u-joints, Ujoints are engine rpm releated
and did you get a alighment? |

My car does the same thing. I cant listen to my CD player anymore cause the vibration is so bad the cds skip. In mine though the vibrations start at about 40 mph not when im at a certain rpm like shane. If it is the U joints how easy are they to fix?
|
The U Joints on the D/S aren't replaceable (unless you have them machined)...You have to buy a new D/S or a used one with low miles...I recommend buying and new one or a remany, as I've bought 2 used ones a BROKE both of 'em. New D/S goes for about $239+.

Not that I'm aware of..every one I bought you couldn't replace. I think thats with all D/S from (2ndGens-My only exp)RX7's.

ok its not the u joints but the rear tranny mount is in pretty bad shape so im gonna go with that being the cause. also if you get a new ds you can get them with replaceable joints, or you can find a shop that will cut the ends off and put new ends on that have replaceable joints. there is a place here in my town that does it and its a small town so look and ask around someone there might do it to. oh and the u joints arent that easy to get to bc you have to remove the exhaust to get the ds off. look at the fsm there used to be one at fc3s.org but it hasnt been there in a few days.

U-Joints in the driveshaft AREN'T engine RPM relative. They're speed relative.
the car in nuetral at speed it would smooth out, back into gear it would vibrate again, so when under load the ujoints caused the vibration |

I know on 2 cars of mine that had bad ujoints when I put

If there is vibration at speed, then there is too much slop in the driveshaft u-joints, and they need to be replaced. I can't see it being in gear a problem, unless there is another underlying problem that contributed to driveline vibration. Especially not engine RPM related at all. Maybe if the driveshaft was bolted to the flywheel, but... |
yes- I had a car that I cracked the stock u-joints a few times.
A big block in a car that had a 6cyl tends to do that, lol. under load the vibration was terrible, if it wasnt under load it wasnt that bad. you have to visualize a cracked u-joint, when there is more load put on it it will get worse, when there is no load it wont be as bad |
Yeah if it was cracked, that's another story from just having wear slop in the joints. Power application would flex the cracked joint and make it vibrate like hell! LOL. I don't think Shane is making enough power to crack his u-joints though.
|
slop in the joints would still cause more problems when under load
|
You can take your existing shaft to a drive train shop and they will put new greaseable, replaceable u joints on your shaft.
Had mine done last week for $116 |
