top shock mount stuffed. HELP.

[dan dog]

Fitting new suspension and have hit a shag. the top rear shock mount has the thread stripped off it. anyone had this happen to them? How did you fix it? Or any suggestions on how to fix it. my thoughts cut the old one off and weld a different on. any other suggestions is more than welcome. thanks in advance. Dan.

Call me a dummy mate, but genuine question in trying to assist -- what does " tread stripped off" mean?? I've replaced multiple rear shocks, but unfamiliar with the term is all ...

[dan dog]

The top shock mount that goes through the eye of the shock has a thread that a nut goes on to hold shock in place. The thread has stripped off so nut will not do up.

[dan dog]

My bad. Sorry didn't see that I spelt it wrong.

Ahhhh - sorry champion, should have picked that one ....

Do you have a tap and die set? Any chance of salvaging the original mount by throwing a die on it and creating/repairing the thread??

If not, then I can only assume replacing it as per your original post would be the go ...

Hopefully others can assist also mate - pain in the @rae job either way by the sound of it ...

[dan dog]

first thought was to re-tap it. though not enough room to do it. thinking i might have to cut it off. OR im not sure on this but can I heli coil the shaft and use bigger nut or does that only work for screwing bolts into the heli coil.

Happy to be wrong, but I thought helicoils were only for holes .. not shafts/bolt stems. Sorry mate, can't help on this one unless someone else knows if they can be used.

[dan dog]

yeah thanks mate.
i dont really want to cut it off. but its looking like im going to have to. i never heard of heli coiling a shaft either but it was just a thought. oh well the joys of cars.

Good luck with it mate, as said, prick of a job either way ...

Let us know how you go.

Dan Dog,

You could try cutting a new thread, with a similar pitch. For example, if the current thread is a fine thread 17mm - try cutting a fine thread 16mm with a tap and die set and some lube ( Make sure you can get a suitable nut first ). You need to keep it a fine thread, as this will give you a better holding strength - don't use a coarse thread.

How did you strip it by the way?

can you leave the shock alone, and use coil spring compressors to crush the coil and get it out? Even trap the coil in the compressors by jacking up the axle and using it to squash the coil?

NOTE: in saying this I have not done it, I do not know if it is safe, and I don't know what it would be like releasing the tension from the spring compressors. Nervous, I suppose, there would be a bit of energy stored up in the system :-)

[dan dog]

I will have to cut it off anyway as there's no room in its location to tap a new thread onto it. I think previous owner has cross threaded it when putting shocks in. Nut came off easy. When I removed shock I seen the stripped thread. I'll put a pic up so you can se first hand. Appreciate the help guys.

[dan dog]

its on passanger side top mount.

ill have a bit better look in the day light. not sure wether to cut to off at the very rear where the flat plate is or where it flangers up then drill into the remaining peice. (i have some old shackle pins which are the right thickness) and recess it into the remaining peice then weld. (if that made sence).
open to other opinions. because i really have no idea witch way to go about it.:icon_bonk::icon_bonk::icon_bonk:

spring and shock are already off. im putting new stuff on it. but this has really put a damper on my day.

yeah, just worked that out, I think :-) I had the bull by the tail and thought we were talking about a spindle ended shock rather than the mounting pin for an eye end.

while looking at it in daylight, is it worth checking to see if it is attached like a wheel stud, ie pressed in from behind?

EEK. have to pull fuel tank out to do that. but not a bad idea. ill check the drivers side one cause i think it was clear of the fuel tank. if so probably lot easier to remove tank and knock a new one in than cutting and welding. i'll keep you posted on that one. thanks

[dan dog]

Curiosity got the better of me so went had a look. And there welded in. So looks like its back to the drawing board.

[patch697]

Having a look at that pic, Im thinking it maybe possible cut a hole in the floor pan to gain access with a dye & retap the thread that way. I know cutting the floors not everyone's & it may very well not be yours either, but im thinking of it from a work involved type of aspect & lets face it. a hole in the floor is quite easy to cover & seal up as apposed to the amount of work involved in cutting it out & welding in another one.

Just a thought.

[dan dog]

Thinking out side the box. Good one. May well be a option. At the moment can't sleep trying to get my head around how much of a bast@rd of a job its going to be. (Which ever way I go about it).

[nissannewby]

I know its been said before but grab yourself a die nut that way you can re thread it using a spanner. Die nuts are good as you dont need the T style handle you can just use spanners,sockets etc. You should be able to get one of these in there as it will be the same as getting your spanner in there to undo the shock mounting nut. Failing that it looks like a cut and re weld.

[nipagu7]

x2 on the die nut . Just make sure you thread it on the right way ( tappered threads first ) and go easy and let it pick up the old thread and use lube .

[mrflibbles]

die nut x3, they are awesome for spots like this!

[happygu]

Dan Dog,

This is what we are talking about....

Where you can use a die handle, and even unscrew one of the handles to get around the difficult spots, or just use a spanner or shifter.

[dan dog]

Thanks everyone. Didn't even know you could get them nuts. I was thinking big T handled die. I'll give it a shoot. Again thanks for all your input.

[dan dog]

:trink13:VICTORY. Nut die worked a treat. Thanks everyone for your help. So happy right now my. @rse cheeks are clappin.

Alright, thread dig.

I have a problem with mine except mine snapped off and have been searching high and low over the internets and I'm out of ideas on how to fix mine. Pics incoming.

[Count Grantleyish]

Anyone got any ideas? Or I'd best cut my losses and part it out?

[Ben-e-boy]

Easiest and cheapest way would be to drill and tap and use a bolt with a large washer to hold it on.
Or, get a complete shock mount and weld that in.

[Count Grantleyish]

Sounds easy with a ute not in a wagon :/

Body off to access these...

[Count Grantleyish]

Thanks again for the suggestion, will have a think whether it's feasible to go ahead or not.

[Ben-e-boy]

No, just get from underneath. No need to remove the body

[Count Grantleyish]

From what I can see, there aren't much room to use the drill of any sort even if I take springs out.

[Ben-e-boy]

Well, that just leaves cutting the old mount out and welding anew one in

[Count Grantleyish]

Yeah, prob cost fair bit in labour since I don't have space and tools for that job.

Thanks again.
