Do i loktite propshaft bolts please?

A small drop will not hurt and if too hard to remove a little heat from a hot air gun usually softens it.
I recently had a crankshaft pulley bolt that was originally tightened to 70nm plus 60 degrees, that I couldn't undo with a long 3/4 drive bar or a 3/4 drive impact gun, but a few minutes with the hot air gun released it. On removal I found it had been previously plastered in Loctite!
I was quite relieved as I had heard of Dealers with the same problem presenting the customer with a bill for a new crankshaft a few years ago!!!

So works are completed.
Removal was relatively straightforward the bolts are allen key which is unpleasant in so much that they are unforgiving if you're struggling to undo them. The shaft was stuck in each flange as there is a dome on each end of the shaft into the mating face. A swift bash in a front to back direction got it out.
New shaft was a beauty and fitted perfectly with further allen head torment when tightening.
All in swap out time was 2 hours

And the problems you were getting are now all resolved?

Road test next. New clutch and DMF is preventive maintenance

I thought I had finished all my work on mine but I fear the rear differential is giving up.

I had the brake fluid changed when the new turbo was fitted. The clonking last week was the fact the wheel nuts weren't done up and n/s wheel nearly fell off

Mine feels like it is slipping on the drive axels. I’m hoping it may be a CV joint but I think it is actually a new rear differential needed.

Second hand unit?

Second hand unit?

Second hand are pretty expensive and it’s entirely possible that it will then go again if it has come off an earlier 2013-2014 panda

How much are new ones?

I think a new one is about to£600. That second hand one you posted doesn’t look like it could be off a 2021. If it is it has not faired well. My 2013 one looks in better condition than that

@euroben Very rarely is any drive sent to the rear wheels, so are you sure you have a rear drive issue? (Only transmits drive if the fronts are spinning on mud or snow.) You can force 4x4, but that is not advised when its not needed ( and must never be done on tarmac) as it leads to potential damage through wind-up (as there's no centre diff, if 4x4 is forced on a grippy surface there's no where to release any front to rear rotational differences)

To be honest, I have run out of other possibilities. I have replaced everything else . I seem to remember in the manual it says that about 10% of power is pushed to the rear wheel under normal driving but I’m not by my manual to check. I also don’t drive with the ELD on ever. I can’t really see many opportunities where you would need it.

When i put my car in gear to remove the propshaft the drive is definitely to all four wheels. When i then drop it into neutral and turn the prop - all four wheels rotated

 

[Herts Hillhopper]

Yes, there is always a small amount of drive through 'stiction' in the system - Fiat claim 98% front drive - but technically there is no real power being transferred there in normal use.

Its all turning all the time. Rear drive only happens when the clutch activates in the rear diff and allows thediff to accept drive from the turning prop.
