U-Bolts one time use only?

So once you loosen u bolts once they are suppose to be replaced?

 

Yes, the threads on the u bolts distort when torqued.

 

Part numbers anyone?

 

Stock length?

 

Yes

 

I use these, high quality, grade 8, and good price. Would need to cut excess off after install.https://4x4.fatbobsgarage.com/toyota-tundra-rear-axle-u-bolt-lift-kit-2005-2017-p5749.aspx

 

Would it be dangerous to drive on them for at least 2 or 3 more days if I have removed them 3 times now?

 

People reuse them all the time. I think you’ll be fine for 3 days.

 

What about after market u bolts? Im planing to replace my blocks 2" to 1" looks like my truck is nose dive

 

Are you supposed to replace them? - YES
Do you have to? - no

Stock Toyota hardware is more why, cause it gains strength by stretching when torque....if you go aftermarket (grade 8 or something) you can re-use no problem

 

I placed some on order today

 

If anyone needs stock U-bolts that are rust-free, I have my mine that were taken off my truck new at 5k miles.

 

It is not about them stretching, the rolled threads on the u bolt deform from the engagement of the deep nut. This is what locks the nut and holds the torque. That said everyone do as they want, I don’t care, just thought I’d explain.

 

Do you still have them?

 

Yes.

 

Ha! Put them in the trash can where they belong.
