CV or diff?

[Stevie D]

My newly aquired 110 csw has just developed an alarming (heavy)clunking noise from up front somewhere, at least thats where it sounds like its coming from Not had it a full week yet.

Very evident on acceleration and engine braking, thought there was a faint noise on slowly freewheeling the other day - but put it down to tyres, and most definatley on full right lock, clunk, clunk, clunk.

Nothing obvious from a look underneath - wheels aren't rubbing etc. No major oil leaks, chrome nice and shiney and moist with oil on the swivels.

Only thing is a bit of play in the prop shaft about 10th / 8th of a turn slack between front diff and transfer box.

I'm suspecting the cv, but could it be the diff or something else more sinister.

What tests can I do to prove or disprove this other than jacking up that wheel and spining it. How big a job is it, what will i need, or is it easier to buy another axle?

The vehicle had sat for a while and i've done about 350 miles. Oils etc were all changed about a year ago by po.

Thanks in advance

I'd jack & axle stand the front end & put the steering on full lock each way in turn & see if the clunking is evident that should help pin the noise down

has it been used off road? crown/pinion?

A worn CV will normally produce a Clackety-clackety-clack, more pronounced when in reverse.

I'll get it looked at properly at the weekend, think it's likely to be the cv tbh. Hasn't been used off road much afaik, po had a challege truck for that.

All parked up until then just in case.

Cheers Folks.
