| Cradle Bolt question - To threadlock or not? (Page 1/2) |

Just curious if anyone thinks it is a good idea to apply, at least orange or blue, threadlocker on the cradle bolts?
The only thing I may worry about is the rear ones, if I do apply some removable threadlocker, and decide to remove the cradle in the future, if I would be putting the cradle nuts in a jeopardizing position where they would break and spin.
Maybe I'm just overthinking it. There is really no rust and they came out without a ton of effort, so maybe I'm ok just slapping it back in without threadlocker.

I believe the nuts are swaged, but I would share the concern about breaking the cage nuts free if a thread locker was used. My 87 cradle has been out about 4 times since I bought it in 2001. Never any thread locker. Never an issue with the cradle bolts coming loose. Just make sure they're tightened to specification when installing them.

No thread-locker needed.
Most cases the rust acts as thread-locker. Anti-Seize may be better and torqued properly. Research dry torque vs wet torque.

Thanks everyone.
I was checking on some past PFF threads about this. Seems like that anti-seize is a go to for many people. Wet torque value seems to vary between 25% to 40% reduction vs dry.
There seems to be a debate that purple threadlocker is really good as an anti-seize. I've seen orange in a lot of GM factory applications on newer vehicles, especially brake parts.
Maybe I'm overthinking this and I should just go to dry route. I was able to unbolt the cradle bolts without any issues, so maybe I'm ok to put them back in without worry about them seizing. (I don't plan to drive the Fiero in the winter nor do I live in a high road salt use area).

That orange stuff is Brake Grease. Sounds contrary to common sense but it's to keep the caliper slides from hanging up. I use it on all brake work. So be careful when you tell everybody to grease their brakes, lol. Silicone and Ceramic versions.

Somebody posted this info years ago.
Rear cradle M12 X 1.75 X 70 mm long for 84-87 and 50 mm long for '88's grade 10.8.
