Changing Rear U Bolts

Hello Everyone,

Am planning to install some Durobumps Bump stops for the rear and changing out the u bolts as well (from Toytec). FYI I have a 2018 crewmax.

I am planning to do it on a flat level surface (aka garage), my question is do I need to still put the truck on jack stands or can you swap the u-bolts while truck is sitting on the ground like normal (with wheels attached etc)?

I've seen a couple of videos of people changing u bolts without even lifting the truck but would like to hear your thoughts on the matter.

Any help much appreciated. Thank you in advance!

 

First off, glad to hear you're replacing the u-bolts. U-bolts are not supposed to be reused. I torque mine with the truck on the ground. Be sure to re-torque after a few miles.

 

A couple years ago I installed SumoSprings on my Tundra. I parked on my flat garage floor, blocked the front wheels then one side at a time removed the u-bolts and stock bump stops. New u-bolts and Sumos torqued down, then as 831Tun mentioned re-torque after a few.

 

Yeah, you can do it on the ground, but taking the tire off will give you easier access to them.

 

Thanks for the input, guys!

 

One at a time on the ground is fine. When I replaced mine I snugged them all down fairly tight and then torqued them in an alternating pattern. 74 foot lbs.

 

Definitely pull the wheels to do em. If anything it'll be easier when it comes time to torque them down to spec.

 

I followed this sequence

 

I put durobumps on the rear about a year ago and I did it with the wheels on and on the ground and I took weight off the axle and leafs by jacking up the truck a bit by the hitch. Works great and it gave me more room too.

 

Agree with the comment on the crisscross bolting sequence. I usually go to 25lbs of torque and cycle through each nut, then go to 50 and cycle through and then finally 74 and cycle through. Seems to give a nice even torque all the way around with even thread exposure. Not sure if that makes a huge difference in the grand scheme but its always made it a pretty easy process.

 

This is a good option if you aren't on a tall lift.
