Took my SR5 off road recently and noticed a rattling sound in the front end caused by a loose upper control arm bolt. I did get a Westcott preload lift but the installation did not require any work done on the UCAs.

I spoke with Toyota and apparently it's supposed to be torqued to 140ft/lbs.

Just an FYI, may be worthwhile to get this checked on your vehicles!

Sine you changed the ride height with the pre-load coller, you actually should loosen the UCA bolts and retorque at the new ride height.

You should do the same for the LCA and lower shock bolt. The sway bar bolt on the LCA might need this done too.
