Tdi Clutch bang or back lash?
When changing gears some times I get notable backlash.

I also notice if you push the clutch down and let it spring up you get the same sound.

Seems worse lately as I stood it up in the first lockdown and the brakes got rusty and there is a rust spot on the disks causing a vibration when braking (felt through pedal!) It sounds like its trying to catapult gearbox through floor!

Any ideas what it might be?

I'm just worried I'm causing damage to something? New brakes waiting to fit as soon as 110 is back in action.

Could be the handbrake drum grabbing. Try backing off the adjuster and see if it cures it. Just be aware that you might not have a working handbrake whilst trying it! Darren

Brand new props front and rear.
I will double check hand brake but sure that's fine to be honest.

I think its clutch and possible slack in transfer box but its strange as the clutch makes a strange bang.

I just don't feel up for pulling the box at the moment. Big Cry

I fitted brand new props front and rear.

It's just like that noise but from the clutch housing or box. Also done the rear a frame ball.

It's just the sort of thing you hear and expect to find out what it is.....when it breaks Big Cry

The LT77 where coupled with the non drilled input gear in the transfer box which wears the LT77 main shaft. But if there is excessive play in the splines, sure that the play did not happen overnight. So why happens now? As with the brakes rusting, could also be the flywheel and pressure plate rusting and biting a bit more on the friction plate? 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing

I remember about the spline wear issue and hoping its not that.

Do you know which suffix boxes was affected or was it all LT77 & LT230 combinations?

I feel like possibly something like flywheel and clutch plate issue? When I bought it originally it had a TD5 and auto box but converted to 200tdi so not sure of work carried out.

I know that the spline wear went on to some R380s with 300tdi as well. But cannot say at which LT230 suffix it was fixed.
If you have the original LT230 from a 200tdi era motor, then most likely the input gear is not drilled, unless someone replaced it.

Do you also get clutch judder? 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing

No clutch judder.

It's just when you release clutch you get the noise.

I guess with the spline wear there is nothing I can do now if the wear is that bad so just wait for failure?

If I can I will video and show you. Thank you for your help.

I would take the PTO cover off the transfer case and have a look inside, at least you can gauge how bad it is, and if it is it after all. Put in 1st gear, then either jack one wheel (front wheel and can keep the handbrake on, difflock disengaged) and rotate back and forth that one wheel and see how much play is between the gbox mainshaft and the input gear.
The problem of waiting until it fails is that it can fail miles from a cheap recovery, unless that is not a problem. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing
