Loctite for lower rear shock bolts

[rzepko6194]

Ok, this all started with a broken head stud and oh look, I can see the top of the rear shock nuts, now that the engine is out. Guess I had better replace them. Although, I have to admit that the original Boges, even with only 17K miles, are pretty soggy compared to the new Bilsteins.

I noticed that the lower rear shock bolts have a red substance on the threads. Given the effort required to remove these, I assume that it's red Loctite. Should this be used again on reinstallation or should I just clean up the threads and reinstall dry?

I think you're looking at a red paint mark from the factory which likely indicates the fastening was "complete" or the proper amount of bolt rotation ( indicating torque) was applied....not loctite

No, it's not the red paint mark on the bolt head. It's reddish-pink stuff on the actual threaded part of the bolt. It was fairly tough stuff to wire brush off.

I don't use loctite. Actually I use antisieze on the threads to make sure I can get the bolts out later. Those steel bolts going into aluminum threads can almost guarantee that they will lock tight all on their own.

I did the same as Kurt with antisieze.

Thanks guys.

Loctite does not retain it's color when cured.

I believe you screw the bolt into a captured steel threaded insert that is in the aluminum banana arm. I don't believe Loctite was used...but may have it from the actions of a previous owner?

I doubt it with that kind of mileage and the fact that these are the orginal shocks, but you never know! Maybe the factory was using some wierd tinted antiseize paste.

Most of the antiseize that i've seen Porsche use is the copper stuff.

The lower shock bolts are typically stubborn. I agree that Loctite was probably not used, but you never know. I know the factory didn't use it because my microfiche repair manual states the torque specs and any antiseize or threadlocker needed for any fasteners. No Loctite that I can remember mentioned in my fiche.

Use antisieze and torque to spec (95lbs?). Those bolts are so long that red or even blue loctite would make it very hard to loosen.
