Default Replacing Bumper Myself - Advice 4 the Noob

Have recently learned about Loctite, Anti-seez; still not sure when to use which, but will likely use Loctite Blue for the bump bolts) wasn't even on my noob radar.

Now wondering if there is anything else I am missing (like...what percent torque w/ Loctite?)

Anything else I should know about (that a rookie might miss) before tackling this job?

Going from stock JK to Expedition One Basic DX.

TKS

just FYI..I didn't use Loc-tite or any type of anti-seize when i swapped bumpers. Maybe if you plan to keep the new bumper on forever maybe, but if you decide to upgrade..its gonna be a pain to take it off..

Unless there is a specific torque setting specified, just use PFT torque.

Anti-seize or never-seize. is used to prevent threads from rusting up. I have taken apart 20 year old bolts with never seize on them like they were new. Loc-tite is used to prevent threads from loosening up from vibration. so something that shakes or twists a lot would be a reason for loc-tite. For bumper bolts use never seize. and torque them. However never-seize acts like a lube. so torque specs will change a bit. It will be tighter than the wrench is set at. not sure how much. it may be negligible.

Do not use loctite on your bumper! Thats mostly for low torque bolts that might loosen up over time. You can put antiseize on it just make sure its torqued and watch out that stuff is extremely messy

Agreed. I have gotten into the habit of antiseizing every bolt on my jeep. A little bit goes a long way, no need to cover the entire bolt with it.

After rebuilding two CJ5s anti seize is my friend....it will make your life easier in the long run

I have been a Mechanic all my life, and I can tell you from experience that Loctite is over-used in many applications. If you ever, for any reason have to remove any fastener on your bumper, it will be more complicated.

Additionally, the standard method for removing high strength Loctite (red, I believe) is heat. Depending on the location of the fastener, and the surrounding materials (plastic, painted metal) this may be impossible or impractical.

Proper torque, can be achieved even without the use of a torque wrench. A typical 3/8" drive ratchet and box end wrench are not long enough to over-torque (stretch) a fastener. So...snug/tight, but no cheater pipes or breaker bars.

Just my 2 cents...

I only used Loctite when mounting my winch, and that was for anti-theft purposes.

You won't need loctite. The bumper bolts have crush washers that keep them from loosening. Just make them good and snug and you should be all good. It's pretty easy so I wouldn't worry too much. The hardest part will be getting all the stock bolts out.
