Ever since I bought the truck, my hubs and lug nuts are screaming hot. Over 400F degrees. no way I could touch. Rotors get blue, you know what i am saying. So let the labyrinth begin. I figured since the J10 was sitting on a farm field for 2 years and burred in the earth - i would have to change some things Thought this would be a fun project with my 13 year old, teach him some things and when he turns 15 - this year- he will be able to get himself a Jeep and start the process over. Thus far, its bee amazing but this one issue.
For full transparency, we have replaced:
- Hydroboost system from Elliot ( he is on here - AWESOME DUDE!)
New PS Pump and Box
New Manual Locking hubs ( with bearings, race, lock nuts, grease,etc)
New lug nuts and lug pins
Steering shaft with Ujoint system (Borgeson)
New Water pump
New Steering linkages
New Ball Joints and U joints
Knuckles sand blasted and re painted
2x New Prop Valve (Tuff Stuff)
2x New Calipers
New Stainless Steel Brake lines
All new Brake rubber hose to caliper
New Drum Brakes
New Suspension - Skyjacker
New 600 Holley carb
With all of that changed, our hubs and lug nuts are 400 degrees. As you can see we have "2x" by the calipers and prop valve. My calipers were getting hot (110F is that hot?) and I could not move the caliper. Slider pins were stuck. I greased them and figured that was the simple fix. NOPE.
Moved to the prop valve. I had a CCP valve and didn't realize those were made in China. I did some research an many blow through them and thought that I have found the problem! Naturally, my bias was off and fronts were getting all the pressure. This could have been done from the initial bleed. I have then invested in a prop bleeder tool. PS - all mechanics never heard of this tool.
As much as it has fixed a lot of the heat, as it is, it still is causing some heat. The good news after replacing with a TUFF STUFF prop - my new temps are 135F at the nuts, rotor and hub. Caliper is 100F. Still hot in my opinion but ya'll tell me. No spit sizzle and can manage 2-3 secs holding onto the lug nuts. It seems the lug nuts are the hottest in every attempt to fix.
I have heard so much from mechanics:
- need to convert to all calipers b/c all calipers are reman
-Hydroboost is too much for that Jeep
-axles are old (they have never pulled them out so not sure what they are saying here)
-Warn hubs are the wrong ones. (not according to WARN when ordered and confirmed)
The only thing I have not done is change out the front diff oil. Could dirty or lack of oil create that friction when the wheels are turning? We have the front shaft disconnected b/c we replaced the welded gears in rear to 4.10. Therefore when I get more money, I can finish the fronts.
Any help would be great. Anything i have not thought about? Not sure if its me or the J10 being stubborn but I need help as I am tired of this one issue.
