    I am looking for an reliabel adres for restore my differential. I have the "clunk" if i change gear.
    I think to much play between pinion and crownwheel. I also have vibration from the propshaft i think.
    Adresses also in Germany is possible.

    Might be UJs in the propshaft. Cheap to change.

    Or diff mounts

    Or the UJ's in the driveshafts.
    Vibration from the prop could be incorrect alignment.

    Also if the mount at the front of the diff extension, a misaligned engine or broken engine mounts.

    I test drove used P6 at a garage and the front diff mount bolt was missing entirely , clonk when changing gear and horrendous banging in reverse.

    Apart from the output shafts, I've found the diffs to be pretty reliable, they don't suffer with excess backlash, they don't get noisy, and apart from the aforementioned output shafts, I've had one pinion shaft snap, and one set of planet wheels grenade themselves, and apart from the myriad of oil leaks to fix, that's been about it.

    Can anyone confirm the very last F-series diffs in 2200s did indeed have the extra pair of plantery gears? I've heard differing opinions.

    I 'll check these points and hopefully will find the solutions. The engine mounts are new and the two half sections of the prop shaft are correct together with the marks allignement.
    One universal joint of the drive shaft is not good so i will replace this one. Thanks for the comments!!

    I can't confirm but that was my understanding as well, all late cars got the V8 carrier & spider gears.

    Problem solved. The 2 UJ's from the drive shaft. There is no "clunk" and there is now play. I also changed one wheelbearing and the dion elbows because there were little holes in it.

    Good result. It pays to ask!
