Halfshafts falling off - WTF??

[thornado327i]

Ok. Had to wait for a descent wether.

Got under there, bolted the halfshaft in place. Still need one more bolt - currently running on 5. Didn't "glue" them yet - will do that as soon as I get the missing bolt.

BUT

I took a car for a drive up and down the street to check stuff, and... At about 40mph there's a silent "thumping" noise comming from the back. When I put more pressure on the left wheel (turning right) the sound gets louder.

Any ideas? Hub bearing? Halfshat? Diff? (God forbid - try to get a descet LSD here).

I prefer the Wurth stuff, i thik the Blue meduim strength would do the trick, the RED high strength would be a bitch to remove with out torching your seals

Thanks for the reply. Exactly what is "loctite". From the sound of it I assume it's some sort of compound for "binding" bolts... Correct?

Please give me some details about it. I'll have to look or some sort of equivalent of that on our market...

use some loctite. it'll fix that problem. i've had this happen on a few of my cars now, pretty annoying. just keep an eye on it after tightening them back down to spec

Here's an interesting issue - upon replacing my exhaust, I noticed that bolts holding halfshafts to the diff were a bit loose. So I tightened them and forgot about it. Figured that I must have forgotten to do that when I was putting the diff (a year or so ago).

But that was 2 months ago.

Yesterday, my left halfshaft fell off... I jacked up the car, took the wheel off and noticed all bolts were just hanging there along with the halfshaft itself... Got loose and fell off completely this time. One bolt got bent making it a bitch to pull out of there...

The halfshaft itself looks ok. The rest of the bolts seem fine too. So WTF?? Anyone had any problems with that? Never happened on my previous two diffs (open ones - my car ate them with delight).

Any ideas how to make them bolts hold? Glue them in there or what...

I got so pissed I forgot to check the other side too - will get under there on tuesday.
