Car Forum / Driving, Maintenance, Tuning / General Car Topics / March 200690 Ciera vibration.. HELP!
Thanks for reading.... My daughter's 1990 Olds Cutlass Ciera started vibrating on acceleration. I took it out on a test drive and it seemed pretty obvious it was a CV joint. I popped the wheels off and sure enough.. grease everywhere under the passenger wheel and a nice slit all around the outer CV boot. I bought another axle and put it in. On the test drive it was now thunking whether on acceleration or not. Not the same way as before. It was now almost bouncing. Not affecting control of the car. I don't really feel it much in the steering wheel. I assumed it was because of being so far out of alignment. Took it in had it aligned. Driving out after the alignment, the thunking was even worse. Same thing just a LOT worse I wasn't sure I'd even get it home. I got it home and pulled everything apart and put it back together again. Everything appears fine..but it's not. I put the front up on jackstands and put it in gear to see if I could see firsthand what was going on. When I hook up a wrench and spin the wheel, everything seems to be smooth. I spin the wheel, the other spins the other way. When I put it in gear and give it some gas the thunking starts again and the passenger side of the engine jumps up and down, particularly when giving it gas. I made a couple .movs of it, but I don't know if they help much. The first couple are just showing around the area, then one shows me turning it with a wrench, and the last one (or two) show it running in gear. I tried to show the jumping from under the car and from above, but the anti-jitter in the camera kinda cancels it out. At some points you can see it. Could it be the axle I got was defective, a tranny issue, a broken motor mount? NAPA said they'd replace the axle under warranty, but I'd rather not do that if the problem is something else. If it's the tranny, the repair is not worth it. If anyone has any advice I'm eternally grateful! http://www.iceohio.com/ciera1.mov http://www.iceohio.com/ciera2.mov http://www.iceohio.com/ciera3.mov http://www.iceohio.com/ciera4.mov Joseph This can be typical of a bad inner cv joint especially with the engine moving around, one of the common symptoms of of this. > Thanks for reading.... > [quoted text clipped - 43 lines] > > Joseph Check the wheel bearings, the inside bearing will be bad. > Thanks for reading.... > [quoted text clipped - 43 lines] > > Joseph How sure are you about the wheel bearings? Replacement is $90 :( Shake the wheel, if it is loose at the hub and bearing it's possible. > How sure are you about the wheel bearings? Replacement is $90 :( Shep/Mike, It feels pretty tight... But I'm trying to move it w/o the wheel on it. This is a tough one for me... because I can see how the wheel bearing might have been damaged when I was taking the old axle out. The Haynes book said to just take the bolts off of the strut fork and pull it forward. This was bad advice. I had to take the bottom one off too. In the process I had the old axle invery awkward positioning. That could have damaged it. But... I still don't see how the bearing being bad would make the engine hop when I'm spinning it without the wheel being on it. I jacked the front end up, took the wheel off that side and ran it about 10MPH and it hopped like crazy. If I hook a wrench up to it and spin it from the hub it seems smooth. If it IS the bearing, replacing it would proably be worth it. It'll put the car back on the road for a few years. If it's not... Say it's the transmission... I've just sunk another $100 into a $800 car that's heading to the wrecking yard. Again frozen inner cv, won't slide in and out, pushs the engine around on its mounts. > Shep/Mike, > [quoted text clipped - 16 lines] > the transmission...

He gave me the axle for the 3 speed w/o the OD. They are damn near identical, except the 3 spd one is a little longer. He caught it when I took it in. He never really admitted he'd messed up, and seemed to be bracing himself for an asschewing... But nah.. honest mistake, and the correct one fixed the problem. My only pain is install/remove about 4x too many... well and another alignment :( I'm hoping to get a discount on a re-alignment. I couldn't get the toe-in anywhere near correct, so it's gonna have to be aligned again. But the good news is... The car is back going again :) |
