I hope you mean 1" blocks, not 1 foot . If it is 1", you'll have to raise the frame with the RR axle suspended (hold the vehicle up with floor stands), then raise the rear axle with a floor jack just a little, undo the u-bolts (you might have to use longer ones), slip in the blocks, tight'in the u-bolts back up (95 ft-lbs.?) and you are done.This may sound like a dumb question, but what is the best way to install 1' blocks on my tundra. I understand the general process but do y'all have a certain way that you like to do it? Thanks.
