Replace ball stud on tail gate hatch

[conant]

The ball stud that the piston attaches to on my tailgate has come loose.
It appears to be epoxied in place. What is the correct way to fix this / replace

The pdf drawing you provided seems to show the ball is threaded so if there are some flats machined on the base, (which it looks like there are) that would be to put a spanner on to screw it out (or further in...)

Unless of course a previous owner has bu66ered about with it and epoxied in a smaller threaded ball???

A nice clear close up photo of what you have now might help.

There is definitely a coarse thread on the ball stud but there is no mating female thread in the hatch. It appears that the stud was placed in the recess and some white material (epoxy?) was put around it to hold in place.

I pulled off interior panels but there is no access to this area.

Will take another look and post picture.

It's a double skin there. Drill a large enough hole to allow a socket to tighten a nut as it will never be seen once the trim is back in place

I'll take a look at mine tomorrow (if I remember - got a busy few days ahead...) and see how mine is fixed in place.

4x4's suggestion is a bit drastic but is probably a good last resort.

Thinks... If it's double skinned with no existing access to the cavity, how did the epoxy get applied to the screw threads in the first place??

Googled the problem and found this

thanks for all the info/links..

Might try epoxy first and then mechanical fastener if needed.

I hadn't remembered that the tailgate frame is fibreglass...

The stud will have been bonded (epoxied?) into place initially and I guess that's the obvious method for repair but you will need to make sure the area around the repair site is solid.

Perhaps you may need to scrape away any soft or crumbling material to get a solid repair.

Good luck!! and let us know how you get on.

I'm keeping a close eye on my tailgate now...

You could try a rivet nut which are ment for this sort of application, it may even of been one in the first place.

I epoxied the ball stud in using a 4000 lb strength mix.. Fairly easy to do . Hope it lasts a while, so far no problems.

Thanks for the update Pat

Fingers crossed for a long life repair
