    Hi there,

    Wondered if somebody could help with an ongoing problem on my E46 318i (2.0L) 2003.

    I was experiencing a knock when turning sharp left and right bends, after changing the rear anti roll bar bushes and bush holders we found out that it was the bolt and nut coming lose overtime. See diagram - Bolt number 4 and 5 and also 9 and 10.

    http://www.realoem.com/bmw/showparts...42&hg=33&fg=45

    Everytime the bolt is tightened the knock goes away completely but within days it returns and we discover the bolt has again come loose.
    We have used loctite bolt glue but they are still coming loose, the bolts have been changed and we are now beat and don't understand why they keep coming loose.

    Can anyone give any ideas or advice on how we can sort this annoying problem?

    Thanks very much!

    Daniel

    Replace the nuts for nylock ones and if the problem persists then double nut it

    Can't say I've heard of this before

    Have the threads been inspected?

    It is really strange I must say! Been fully tightened about 5 times now, no probes with bushes, roll bar or drop links, no play anywhere either!
