Changing shocks & removing blocks
« on: September 16, 2015, 06:45:41 pm »
I'll be changing all of my shocks to stock and removing the blocks tomorrow. Do the U bolts get torqued to 150 lbs? Is there any tricks to make or anything I should know about before I tear into it as far as jacking the truck and axles up?

Have an extremely set of Jack stands or Jack under the Axel when you go to unbolt them.
PB BLASTER!!! Remember to take your time with the nuts on the ubolts! Work the nut when it gets tight. What I mean by that is tighten it back down and loosen it until it moves smoother and keep putting pb BLASTER on it. This will keep you from having to cut the ubolts and buying new ones. However, you may still have to get new ones if the threads do not come down far enough. If you do not see threads below the top of the axle tube then you will likely have to get new ones that are shorter.
On the rear be careful not to pull the drive shaft out when you lower the axle or you will loose a lot of fluid if you still have the factory slip yoke from the transfer case. Other than that it should be a simple process. I will have to look up the torque but I do believe it is 150-175ftlbs. I find it easier to lower the rear of the truck just enough to support the weight of the axle and hole the spring perches flat against the spring.
Last thing. Check your transfer case crossmember an make sure you do not have a lowering kit on it. This will change your pinion when you remove the blocks and can damage the transfer case and differential. Most t-case drops are simple round spacers and longer bolts which lower the crossmember to give a better pinion angle and keep the driveshaft in the slip yoke. Good luck and take your time

This is the Ubolt kit that I bought. What are the rectangle shaped pieces for?

they are brackets for relocating the brake lines if you were lifting it, going back to stock height you can ignore those

Should never reuse U bolts, ever!

Don' t bother with taking off the nuts. Just grab a grinder and cut the ubolts but be careful as they can be under pressure.

Very true but I'd be a list to say I haven't! Thankfully no painful or expensive lessons learned!

I've proven 2wd brake lines are longer than 4wd brake lines of the same eras lol.

When you take the tires off, slide them under the truck so if it did fall off the very heavy duty jack stands it won't fall totally flat on the floor

And once you get it setting on the stands step back and shake the truck side to side and front to back as hard as you can

If it's wobbly or doesn't seem stable , fix it before you get under it
