Rear shock absorbers - studs

[High_dan]

Hi guys,

Two of the studs that hold the rear shocks to the body are manky. Anyone know what size they are?

cheers dan

Titanium replacements on there way!

Put them in right way round Dan
Two of mine unscrewed due to nuts welded to stud with corrosion so l just inserted new bolts , Right or wrong?
New spring rubbers here now from Bob so hopefully get it all back together at back end , albeit without fitting the refubed wishbones , do that later (much later) back on wheels so l can get her back in garage . bit of space on drive again then

Original studs are UNC to UNF if I recall and I have fitted bolts on occasion also when the nuts have seized on. But you cant have a long bolt in their so I always end ed up just refitting studs with some thread lock as I always found a UNF nut/washer easier to find if I drp it than a bolt (plus easier to fit) as when the arm is raised the shock will just locate around the studs.

Either way would work for me bob, bolts or studs/nuts but I prefer studs as i always seem to have a surplus of nuts

Strange that they would be UNC \UNF i'd expect that on aluminium casting studs , but UNF bolts went straight in with no sign of using wrong thread ,and just checked old stud and it's UNF both sides. Initially when looked at picture l thought there were different threads so l posted a wanning to Dan about that ,but then l looked again and thought better of it.

Bob, you could be right, they may be UNF/UNF working from memory I might be assuming (and assuming wrong )

High_dan do you have picture of the studs you removed ?

[High_dan]

Hi both, all fitted now and working perfectly, unf both end of the stud. Thanks for the warning bob. That was initially my concern that the threads would be different.

[High_dan]

High_dan do you have picture of the studs you removed ?

look at the threads that went into the body! Was only a couple of threads holding it in.

That's horrible , my guess would be that the stud has been turned around at some time in it's previous owners life ? stripped a nut on the damaged section ,so turned stud around so as to be able to get a nut to lock up.SOD the safety
Which way around are you fitting them ? l would check the depth of thread as l would prefer to put long threaded section into car , it makes sense to me , also worth checking thread in the hole that stud came out of, if it's been rattling about could have damaged thread but if you wound it out ok those good threads might have acted like a chaser or thread restorer .

There is fresh air above the top of damper and the floor isn't there? Mike pointed out that to me, l also found that the original mounting plates had too small a hole to accept the rubber bushes properly , holes were 16mm but spigot on rubber bushes is 18mm so l opened them up.So rubber bushes fit snuggly into mounting plates.

That's assuming you've just bought the shocks? or were they already with the car?

Thanks bob, I cleaned and chased all the threads. The longer section was too long so had to use the shorter end but more than happy it’s connected and safe with blue loctite. Was shocked when I saw that stud, threads still in tact on the captive nut so must have been put in like that.

shocks are new supplied by mike aswell, mine where fine and fitted the original mounting plate no problem.

Did have to trim a couple of threads of the end of shock tho as was contacting the body.

I didn't want do that so made a 4mm spacer which sits above gaiter .
