I've been working on my cars for about 40 years, and was changing shocks on my corvette yesterday - a friend dropped by and asked why I was not using Loctite on the bolts/nuts when putting the shocks on. I never have and have had no problems - thoughts? I stopped at my GM dealer and talked to one of the tech's there - they don't use, but in reading a few articles on the net seems every site is saying you should. Confused I am.
Like you, I've been working on cars for more decades than I like to remember, but I've never heard this before. Never had a shock loosen up, but Ive had more than a few that were a bugger to get off. I think I'd be more tempted to use a little anti-seize than loctite.
I've never used it when installing shocks on any vehicle I've ever owned.
Neither have I, either on my own vehicles or on customers' vehicles back when I was still in the trade, and I've never had one come loose. I did have a rear shock drop on my old '65 GTO, but it was installed by a previous owner, and there's no way to know what he might have done wrong.
I've done suspensions with and without. The true is that when I used without the components never came loose.
I notice for the old J55 brakes I changed the calipers once and the bolts kept loosing off and once I used red thread locker they never required re-torque again.
I've never used it on shocks and never had one loosen up that I know of. As someone else said --I'm more inclined to use anti seize frequently as I've gotten older-- on the chance I might need to remove a nut/bolt down the road.
