Red loc-tite??
I am about to replace my leaf spring bushings and have been spraying the nuts & bolts with penetrating oil. Some of the youtube videos indicate that these bolts have had red loc-tite applied to them. Is this for real? Do I have to heat the bolts up to break the red loc-tite? How much heat does it need as there is no access to the nut on the front of the leaf spring?
I really don't want to break off the nut in the frame. I am intending to use the blue loc-tite when I reassemble. |
I don't think mine did, but with the amount of rust I had you definitely want to use as much heat as you can
If the bolt snaps it's kind of a PITA to knock it out with a hammer |
I just lubed with pb blaster every day for a week before I did the install and it came out fine. But I forgot to lube the bolts that hols the shocks and they did crack in the frame even with heat.

I heated all of mine and they came out of the weld nuts without breaking any. I did have a couple that were seized in the leaf spring bushing sleeves that I had to cut.

I recently replaced my leaf springs. I had also read a lot about the red loctite. I used a propane torch and moved it continuously around the frame where the capture nut is. I alternated heat and PB Blaster 4-5 times, heating a couple minutes each time. Used a breaker bar and got both sides loose without breaking the bolt. One did seize in the metal bushing but I've taken care of that problem before.

I blast a mix of used ATF/turps right up into the frame, with a long nozzle gun, around where the internal thread would be,
use about 1litre, to make sure its soaked, leave it for a few weeks never needed heat, but they are hard to crack loose, I work them back and forth, using 3/4" gear and an impact gun I copperslip all the bolts, better to check them with a torque wrench once a year than have them sieze |
I'd put heat on it just to be safe. Since you're in CA, you may not have the brutal rusting that we get around here, but I had all 4 bushings seized to the bolt and had to do a LOT of cutting.
The original bolts are DEFINITELY red-loctite'd. If you buy Mopar bolts, they'll actually come with the loctite already on them. (I'd have at least a couple of new bolts on hand - even if you're in a low rust area - I bought 6 new Mopar bolts and burned off the red loctite) So if your springs have never been replaced, you will need heat or you will snap off the weld nuts. |

I used anti-seize on the flat part of the bolt where the bushing sits and blue loctite on the threads. So far, so good. :) |
Thanks to all for your comments. It seems clear that I need to have a source of heat for this job. This is a rust-free California Jeep but the loc-tite is a game changer.

Go with the MAP gas and not the propane. It's a lot hotter. Buy 2 tanks.
