#69 of 88 vibration by sandpiper1

My 1991 Stealth twin turbo has developed an internittant vibration that comes in at about 50 mph and gets worse with speed. If I stop then start again, it is gone. Seemed to be from the front end and was strongly felt in the steering wheel. Replace the front CV joints and all was well for a week. Today it was back with a vengence but clearly from the rear. This is a one owner car with 88K miles.
 
Any thoughts??

Did you happen to rotate your tires when you did the CV joints?

No, tires are a month old. They were balanced and four wheel alignment at that time. They went back to the same spot after the CV's.
 
It seems strange to have the the rear CV's go right after the front but I guess it could happen, especially on an old car.
 
There is some speculation it could be in the transfer case.

Well that was my second thought but ti's so odd the vibration would go from front to rear. Has anyone checked the driveshaft carefully?

Other than visual checks while it was getting the CV's plus visual checks a couple of weeks ago when I had the rear struts replaced there have been no specific inspections. I'm going to take it to a Mitsi dealer next week for their expertise unless it gets solved first. I never take it to a Dodge dealer.
 
Anyway, what could be wrong with the driveshaft? U-joints? There has never been any damage or abuse and I am the only one driving it.

Yes the u-joints in the driveshaft can get loose, or even trickier, they can freeze up---look fine but in fact cannot rotate properly---they rotate somewhat on the eccentric instead. Just a thought. A bad driveshaft can kick up a helluva fuss.

Well, you're right about kicking up a fuss. It does that. Kind of strange though that it was in the steering wheel but now is definitely coming from the back. It's going in Tuesday. I'll post what I find out. Thanks.

The Mitsubishi dealer says the intermittent vibration in my Stealth is a tire problem, not a vehicle problem. They found nothing wrong when inspecting the car, so they ran it on a lift and determined the left front was bouncing. They feel it is a balance or a belt problem. My thought is if it was balance it would do it all the time at the same speed. This one is intermittent. If I pull over, then drive off, the problem is gone until next time. The tire dealer did find these newly installed tires were out of balance, especially left front, and have rebalanced. Seems like all I can do is drive it until it happens again. Tires are Toyo Tourevo LS Luxury touring M+S 245/45R17. The tire dealer, of course, says their tires are fine.

I have the same problem. It's a 1W resistor that burns up. I replaced it twice with a few other components and it burned up each time and the display went out. I bought another A/C display and A/C controller and the same thing happened with the display. A LOT OF PEOPLE have had this problem. It seems to be a wiring issue...I'm trying to find out what is causing it.
