This thread is just too funny! Which leads me to ask, "If I roll mine off a cliff will it bounce?"

But seriously, It's better to fix a problem as soon as your aware of it rather than after it breaks( if it's a U-joint, drive shaft becomes battering ram under your car. A corvette not a caviler. Much more costly to fix, also puts other stuff you plan to do with it that much further down the road.) Just saying.

 

I understand what you are saying. My advice is to take it to a local transmission professional (ask others for referrals). You may discover it is nothing or it may be more. Maybe somewhere in between. I use a local C4 guru mechanic and accept that sometime what I wish for does not happen. Corvettes can be costly. Yours is higher mileage. Was the transmission properly maintained. Some drivers can be tough on automatic transmissions and drive them hard trying to make them act like a manual drive model. You may even be able to find a rebuilt transmission for a good deal. Sadly transmissions are not cheap. Do what is necessary my friend. It's not surprising that at more than 150,000 miles your C4 may develop issues like this.

One last piece of advice. You get what you pay for. Fee online advice is not always the best. There are some great guys here. Some have twisted senses of humor. No different than any other online forum. Keep us posted on what happens. Stay focused and find the right expert to find out the exact issue. Your C4 has many years left to deliver memories. Let me know if there is anything I can do too. I am not a mechanic, but can point you in the right direction.

By the way, my first Corvette I owned was when I was 22 years old. The greatest car ever in the greatest time of my life. It was just like yours. In the first year I owned it I had to replace the clutch and rebuild the motor. Is was somewhat rough in shape too. I had to come up with a small fortune but I did. And that car was the very best thing to happen for me at that past time. Thirty years later and many people still ask about that old Corvette.

Best of luck.

 

This IS us playing nice...

If you suspect a half-shaft U-joint, remove the rear wheel and rotate the rotor back & forth. If the diff shaft does not exactly track motion of the rotor service the two U-joints in that shaft.

BTW, when one of those U-joints went bad in my '88 Vette it produced a "click", "click" sound whose frequency increased during light acceleration.

 

If you look real close, it's hard to see for some people, more than likely there is a loose nut behind the wheel.

 

Like silverja said it may be a good idea to get some local help with this because it can get pretty frustrating trying to track down the cause. Hope it's something minor and a easy fix. If you don't mind the kidding you sometimes get here there is a lot of help to be had from this unruly bunch. When they know a person is here for real help they will be there with info. Sorry I'm not much help on this but when I have a situation like this I have a couple of local guys that get me through some of this stuff and a local Corvette club could be a good go to source for you. Theres nothing like hands on help from guys that know these cars. Good luck

 

Seems this isn't a day for mercy.....

 

A friend of mine told me recently that the 700r4 was given that name because it has 700 pieces in it. I wonder how many of those we'll see.

 

I think it will depend on the splatter area and crosswinds (not counting the pieces imbedded in the floorpan)...

 

I thought it was because it was an ""R4" POS
