Uncle Shaughnessy,

Try both motor mounts and the transmission mount. Check for bushing materials separating from the metal mount parts. Severe sag or well compressed motor or transmission mount material can be a clue.

Also, inspect the center carrier bearing bushing for movement within the carrier itself. The bearing may be fine, yet the rubber bushing material may have shrunk and gotten inflexible.

You may also have sever wear in the splines where the rear drive shaft half slides into the front drive shaft half. Many do not inspect the spline for wear. They may replace the carrier bushing and the carrier bearing, yet some may not clean and then juice that puppy up with a slathering of some delicious NLGI 2 grease (like you use for the front and rear wheel bearings) into the receiving side. I mean, really use a generous amount of NLGI 2 grease.

Auto or manual transmission?

Hope that hep-kats.

Hope the fuzzy kitties help.

Hope the fuzzy kitties raid your refrigerator and finish off the buttermilk.

cheers,

dud.

The kitties HAD raided the fridge and finished off the cheese AND the buttermilk in their catnip fueled orgy of fermented dairy consumption, cat scratching post fever, and driving the car like Tunces, the cat who could drive a car, from Saturday Night Live.
