Default Rear end question

Took my car out yesterday and found a strange noise/feeling in the left rear.

While driving straight, I feel nothing out of the ordinary or any noises.

If I slow down and turn, either left or right, I can feel almost like a grabbing sensation in the left rear. I can also hear grinding.

When I stopped for gas, I had to pull around another car and it felt real bad. Thought the tire was coming off! As I pulled forward and the backed up, it felt like the tire was actually moving forward and aft.

Any ideas what to look for? Need to get it fixed before I leave for Carlisle.

Thanks

Russ

EASY FIX, DRAIN THE REAR OF ALL FLUID. ADD NEW GM REAR FLUID AND GM POSI ADDITIVE GO TO A PARKING LOT AND DO SLOW FIGURE 8'S THIS WILL WORK THE FLUID IN BOTH SIDE. THEN GO AND ENJOY.

Doing "figure 8's" is a waste of time and it makes the driver look like a fool. The clutch plates are already sloppy-wet with the old oil and normal city driving will do the same job.

Rare possibility: My truck acted similarly a few months ago.....rear brake drum....when I applied the brakes or turned corners .the emergency brake actuating lever had broken and would lodge itself between the shoe and the drum causing the differential/axle to feel like it was "shifting-moving" forward/backwards.......

When was the last time the differential fluid was changed? I would try that first.

The first time it happened to me was in 1974 when I had a '69 Coupe. A friend of mine suggested changing the fluid and additive. Problem resolved, hope it works for you.
Good luck.

Yeah, Fluid first don't forget the additive. If that doesn't work it could be emergency brake shoes hanging up - Then the biggest PITA, trailing arm bushings shot.

You need to isolate the rear noise as either being the rear axle/differential or rear wheel bearing noise. Make sure you check your rear spindle bearings and yes it is a PITA to change out a trailing arm but not impossible.
If you are hearing a grinding noise in the back or even if you hear an unusual noise be vigilant and keep an eye on your rear spindle bearings. Stop the car and check the trailing arm spindle bearing housing for excessive heat.

I have the same problem. When the car is cold it's ok but as soon as i ride for 15 mins or more it start to stick. I've added posi additive and didn't help. It happen after i apply the brakes to a final stop and i start to move again, it feel like the wheel is grabbing. The wheel is cold to the touch. I wonder what is the cause. I don't want to go very far until i find the problem.

Just got done replacing the fluid. Took 2 bottles of gear fluid and 1 bottle of additive.

The grabbing/clunking is GONE!!!!!!

Fluid I took out was absolutely black!

Thanks everyone!!!

That's why I love this forum, so many people willing to help!

It is a very nice little town but the tourists......
