    Default CV Joint Question

    Do the CV joints rotate when not in 4wd? My concern is i have a squeaking noise under my truck have not been able to locate it. I have put it on a lift run it in both 2wd and 4wd and it wont do it. The sound is almost like a U-joint but i know that is not it but it has a similar sound. Any ideas what it could be?

    Assuming this is the 2000 in your signature, yes, the CV axles will turn with the wheels in 2wd.

    If the noise goes away on a lift, I might suspect something suspension related (a noisy bushing or a loose bolt or similar).

    Ok i will check that out.It is a 2000 classic old body style if that changes anything?
    This might sound very odd but the noise doesn't happen until it rains and whatever gets wet then it makes noise. It has not done it for the last 6 months and we haven't had a drop and now we got like 3'' and the noise is loud as ever. I know it sounds weird but that 's what it does.

    Spray some SILICON SPRAY on the rubber of the CV axles and see if that changes anything !!!
