Mystery awful Rattles, Clicks and Clangs = loose Transfer box MUDSHEILD

[Saffy]

The mudshield (FRC6121) on the front output shaft is driving me nuts. It's become loose and spins around making an awful metallic noise that sounds like the propshaft UJ has failed or a wheelbearing has collapsed or gearbox is about to die. Now and again it stops and then snatches with another scary clatter of a noise :shock: Drove to mid wales and back like this. If I didn't know that it is actually nothing but the mudshield having wobbly I would have probably called for a man in big yellow taxi!

I have managed to fix this is the past by sticking it back in place with a big glob of grease and it went away for 6 months. I had tried a sealant but it doesn't last 5 minutes and then smells as it burns off when it spins again :lol:

Anyone know of any other quick fix before I bite the bullet and try and replace it?

Now this is going to be no use to you whatsoever - But, that may well be whats making an annoying rattle at motorway speeds on mine - its the only thing i hadn't thought of -well done that man, have a bisuit.

It really wont take long to replace it and you know it makes sense in the long run!

I was under impression the flange fixing where special torque up like a Differential but turns out its not, so yeah will replace it shortly.

No more annoying noise from underneath but will just give way to a new rattle or squeek  :lol:

Just did this now, just under two hours.

Flange bolt was pretty tight, had a 18inch breaker bar on it with my foot with me holding onto the tree sliders and the truck in 1st gear low with difflock on (it was slipping with diff off :-. ) before it gave in.

I had not previously released the mud shield is supposed to be fitted to the flange and not seated within the transfer box casing. This made it simple a job of putting a couple of tweaks with center pop in the mudshield and tapping it gently back onto place until it was seated snug on the provided shoulder on the flange.

There was only a tiny amount of preceptable play in the output shaft so the bearing there is still good and the oil seal seems to be holding its own too so didn't need to disturb there.
