Default Rear Driver Side Clunking

This does not happen all the time but when it does I am braking to a stop. I begin to hear a clunking sound coming from the rear driver side wheel. The rate of clunk seems to be fast and then slows down as I come to a complete stop. You would think you had picked up a huge nail in the tire and that is what it sounds like. I have a 92 6-speed.
Thanks

It sounds like either a rear wheel bearing or u-joint. Jack up the back end and grab your tires at the 6 and 12 o'clock positions. Alternating,push with one hand and pull with the other. There should be no movement( like a very solid feeling)..movement usually indicates a bad wheel bearing. You can check the u-joints too if you have it safely supported by applying pressure at the joint by hand to see if there is any free play or using a large screwdriver (very carefully) to apply pressure at the trunion on the joint to see if is flexing.
Good Luck

Hi Tom.

I had a similar post recently, however my clunk begins from the start of the driver side rear tire rotating until about 50 mph. I don't recall it happening during braking.

The majority of everyone who read my post suggested either the u-joint and/or bearings. I determined it was beyond my ability to work on (time and material resources) so I took it to a shop. They confirmed the u-joints, but were not sure how severe the problem was (did it impact anything else).

Since I needed a new Y-pipe installed and muffler eliminators, I told them to get started on it and finish up with the exhaust. I should have the car back at the end of this week (if all goes well). As soon as I have more information back I'll let you know what all happened.

Bill

If only heard while braking let off the brakes at low speed to see if the noise abates or changes.

It was the U-Joint on the driver side. Everything is fine now.... even when I down shift, the car doesn't jerk from left to right... very annoying.

Thanks to everyone for the help.
