Peened in universal joint.

    The UJ on my propshaft is a bit notchy, its got 165,000 miles on it. Unfortunately it's peened in, no circlip. Has anyone had any success in swapping one like this out?

    It's off my 1979 450SL.

    You can see from the picture it is peened in, no circlip.

    but that looks like it has 8 or 9 splines might hammer out with a good punch

    Yea you can grind out the notches with a dremel and then stick them back in with a chisel afterwards.

    Although the last one I took apart I could not find the correct bearings for it so it went to the scrap.
    You will probably have to make a former to beat the bearing caps back into shape as well as they tend to distort as they need pressing out. (Unless you can find a bushing the right size to press them out with maybe)

    There used to be a kit to change them, Moprod I think. A broach to restake them & a measuring thing to make sure the they were in the right place. I borrowed a mates one years ago, but don't know if they are still available. The joint cups on some of them were different sizes if I recall.

    Edit. The kit included a joint, but spares used to be available. It was very much a do it your self kit from the car parts shop, not the motor factors.

    find a local propshaft specialist easier and probably reasonably priced there are a couple with FK postcodes



    I used to work in a garage years ago I used one of the tools to replace a UJ on a morris marina estate the tool was used in a vice to push the new cups in and stake the bores, customer wern't very happy when it failed a relatively short time afterwards when on the motorway

    I'll pop into East Coast Props as it's only 5 miles away and see what they say.

    easy peasy to repair.......cut the cross out, drive the cup bearing inwards to remove......if u can use a rotary flap wheel to remove most of the swagging marks, obviously dont make the bore any bigger.....I usually start with a fine 1/2 round file....
    ONLY TAKING THE LIP OUT.....I'm lucky enough to have an adjustable reamer but really not necc. JUST TAKE UR TIME......it's not a race.......
    anyway once cleaned and smooth push the new joint in in the normal way,,,,, GET IT CENTRAL then take a thick washer 3mm etc drop it in the hole......(I usually turn me own to suit)....
    so 3 good blobs with a stick welder / MIG on the edge will fix the joint......easy to clean off and redo the joint in later years......
    I have done 100's and never had a failure.......my old Volvo did 350,000mile with 1 repaired as above before I scrapped the car......

    I have a Steak bearing tool Moprod PJK1 in box
    Cup size is 1.243Th
    What size are you looking for the actual joint was used long ago 7 the re staking tool was a throw away but easily made on a lathe

    The UJ is 24mm x 74.4mm but If I was to fit a new one I would just go for the welded washer solution.

    From what I recall, the staking tool I used had been used several times, might not of meant to be though
