so i am still chasing down my drivetrain clonk on take up or lift off and this winters job is to refurbish the whole drivetrain.

the GKN diff is on the garage floor ready to be swapped for a refurbished one. I have new diff brackets and have pressed the bushes and sleeves in.

I want to remove the drive shafts and the prop to check/refurbish the UJ's etc.

My questions are:

I assume the drive shafts just unbolt from the hubs in the same way as they bolt to the diff or is it also a splined shaft?

how does the prop come out - does it just slide backwards - if so any tips - what is the best method of pulling it back

do the hubs ever clonk?

finally - renewing the top diff mount - does it just tap out and a new one tapped in or is a pig of a job - I have easy access form above though as my rear shelf is removable

thanks

Correct, 'the same way as they bolt to the diff' and with the same 8mm hex drive.

Just pulls/slides out the back of the T5 and you shouldn't need to drain the oil unless you are removing the T5.

Hubs don't clonk but the CV joins could or make a cracking sound.

Top diff bush can be a pig but at least you have top access.

Sounds like your new garage is warm enough for a little light winter work.
Good Luck for 2018

Steve thanks for the above - last years garage upgrades included kitchen units and sink, a shower and toilet, latex floor, insulation to the walls, heating with radiators fed from the house, a decent stereo, kitchen units and crucially sky TV with a nice 40 inch screen so its a nice place to be.....my only problem is that the ceiling is too low for a 2 post lift - Mrs F has said no to the lift legs poking into the bedroom above.....women can be so unreasonable.

Out of interest, mine is quite clunky on throttle on and off. I had My diff rebuilt by John Reid and he stated that it did have some wear in it which was surprising for 35,000 miles.
I have bought a new diff from Central TVR andit is sitting in the garage ready to go in, in the next few weeks and I'm sure this will solve the problem.

Alun, (classichim) renewed his diff at my place a months ago with a new one from Central TVR and the result was absolutely perfect, no clonking at all, this is what I am aiming for!

Good Luck!
thanks - mine was also rebuilt by john reid last winter so I guess they are just old and tired. Maybe I will buy a new BTR - they are £1050 now. I am awaiting a price from Gearbox man for a rebuild so the decision will be price dependant.

You're not a million miles from me. If you want to stick the Griff on my 2-Post you're very welcome. Pete
thanks for the kind offer - on Saturday I would have accepted but on sunday I pulled it out. it is now with gearboxman in herts for a rebuild with a nice 3.77 lower ration which should give it a bit more grunt......

this weeks evening jobs are to remove the prop and drive shafts - happy days
