Banging from Propshafts

[dan-wilks]

Really struggling to diagnose this by myself, when I attempt to pull forward or backwards I get a small soft bang followed shortly by bigger knocks from somewhere, it only does this when I try to move, I found that the front Propshaft had been hitting the chassis due to two broken transfer mounts which I thought was the problem and have now replaced but the banging is still there.

Any ideas would be much appreciated

It could be your ujs on the prop, what you wanna do is get underneath it and grab the prob sharft and rotate it with your hand back and forth, if there is any form of play in the uj then it is pretty much fooked and you need a new one:

here us a video of one that is really gone but you are looking for similar play:

Brilliant thank you

An update....so replaced one seized uj but after fitting it back together found out that my transmission brake is also knocking!

[gamble63]

have you taken off the transmission brake hub to have a look inside?

[dan-wilks]

no i havent, wouldnt really know where to start apart from get the propshaft off then the locking nut

Thats about it. Prop off, flange nut off and knock the *#%¥ outta the drum till it comes off.

You don't need a fancy tool to get the nut off either. A good breaker bar and a mate, stick it in 4wd and get a mate to put their foot on the brake, locks the transmission up.

If the beating the crap out of it method doesn't work, you could always wind the shoes in

finally pulled my finger out and had a look! turns out the shoes for the handbrake had stuck and left a lump of friction material along the casing which was causing it to knock against that!
