Noisy driveshaft center bearing

I need advice on where/who to use on the north side of Atlanta to replace the center driveshaft bearing on my 76 2002. It abruptly started making noise about 2 miles ago and I haven't driven it since. Also need to know if it's safe to drive a few miles to get it repaired, or if I need a tow. Thanks

sorry I can't help with the shop rec.

but only you can dertermine if you dare drive the

car without incident

You must get under there with a light and look,

push on the drive shaft at the front, the middle,

the back section. Look at the rubber joint(guibo)

closely for cracking or worse. The center bearing/hanger

may have seperated and it's bouncing inside the metal bracket.

Also, are you sure it is the center bearing? I only ask this because I thought I had the same trouble. I had kind of a grindy noise coming from under the center of the vehicle , mainly on deceleration. After the type of investigation c.d. recommended above, I found it was the exhaust bracket attached to the tranny. There are rubber bushings there (or there were supposed to have been) to eliminate the rattle. I put some in and haven't had that noise since.

I shut the engine down and still hear the noise while rolling, so i don't believe its exhaust related. I Thought it might be a wheel bearing but got a mechanic to put it on a lift and listen at each wheel and everywhere else with the car running. He said it sounding like the center bearing to him. he offered to do the job parts plus labor for $400 including a new guibo. I havent checked elsewhere yet, so not sure whether that's a fair price or not.

.....the only FAIR PRICE is when you

do the repair yourself .

Unfortunately with a 30 year old car,

no one can give you an exact estimate because

of rusted, broken, missing, incorrect parts

that add to any labor operation.

Any estimate should state parts prices, PLUS

actual labor time. And the labor time should be OPEN

because of the above conditions of a 30 year old car.

Thanks. Wish I could do it myself. I've done fairly simple things over the years (carb change, alternator, Pertronix, starter, brakes, switch to electric fuel pump, etc.) but none of them risked getting crushed. The parts on it are original as I've had my car since 1979. The center support bearing and guibo are about $80 together so the labor estimate is around $320. It's got 139,000 on it with an engine rebuild at 112,000 (in 1987) and a clutch at 80,000. The guibo looks solid but I figured it should be replaced while the shaft is out. The differential housing is pretty crusted with old oil so I likely need new gaskets that could add to the bill.

If ur in the alpharetta area, I take my wife's Mercedes to German Car Repair. There is also Harrison which I've used for preinstections. Both good and trusted by myself and bimmerforum members.

go for it, it's an ugly job if you do it yourself, and will probably take you a full weekend to accomplish, if you're fast and lucky.
