dave833 Posted November 6, 2013 Share Posted November 6, 2013 Not getting much action on this over on the SVX world network so I'm posting it here, too... The front end of my '94 SVX front wheel drive (not AWD) has begun shakingintermittently at about 60 mph on the freeway- more on curves. It shakeshard for about a second and a half and then stops for half a second,then repeats. It's perfectly smooth up to 60 and smooths out againsomewhat around 70. The other night I removed the front wheels andchecked the ball joints (with a pry bar), checked the tie rod ends,struts, etc., and found no wear or play anywhere. Then I rotated thetires front to back to see if that would change anything. I got the sameoscillation even after doing that. So, I took it to a nearby tire,brake & muffler shop this morning. They spent about 90 minutestrying to diagnose it and couldn't find anything deficient in the frontsuspension either. They did show me that my right front tire had alittle wobble when spinning that indicated a tire with separating beltsand/or a bent rim. Tonight I swapped that one out with a spare wheel& tire I had and it made no difference. Vibration seems to be worseunder acceleration than it is when coasting. I'm stumped-- any suggestions?

Monkeybus Posted November 6, 2013 Share Posted November 6, 2013 Engine/ transmission mounts then? Lock the park brake, keep your foot on the brake, and go from drive to reverse with partial throttle with a buddy looking at the engine from the side of the car while you do this. Also, drive axles can go bad even with good boots on them, but I'd look pretty hard at the engine mounts first. Quote Link to comment Share on other sites More sharing options...
NorthWet Posted November 6, 2013 Share Posted November 6, 2013 Probably not engine mounts: heavy engine and tranny, and engine is absolutely loafing at 60mph. Does it feel like the shaking is up and down, or fore and aft, or ??? Axles would be high on my list to check, particularly the inner joints. Struts might also be the problem, or contributing by not dampening the oscillations properly. Quote Link to comment Share on other sites More sharing options...
Rooster2 Posted November 6, 2013 Share Posted November 6, 2013 a bad half shaft would be a possible problem. My last car had a bad half shaft that would cause front end shake intermittently. I would take the car to a shop, and they could not find anything wrong. Finally, it got worse, and consistent to determine that it was a bad half shaft. A year + earlier, I had a cheap rebuilt half shaft installed. Are either of your half shafts rebuilts?? Quote Link to comment Share on other sites More sharing options...
dave833 Posted November 7, 2013 Author Share Posted November 7, 2013 I've had the car about a year and a half and it's got about 93,000 miles. I don't have any record of the axles being replaced or rebuilt. I've got a couple of spare axles (and struts too) so maybe I'll swap them out and see what happens.

dave833 Posted November 7, 2013 Author Share Posted November 7, 2013 I got underneath tonight and checked the axles-- I didn't find any play-- they both look old enough to be original to the car but the boots are OK. Just on a hunch I grabbed the inner tie rod end near the boot on the right side and shook it hard-- it does make a slight clunking sound and feel. Grabbing the tires and moving them to check for play is difficult on this car because the steering doesn't lock for some reason! Quote Link to comment Share on other sites More sharing options...
