I just got done lowering the rear of the truck.
It was a lot of work getting the old U-bolts off. They were rusty, and there was no room for a saw or anything. I just had to crank REALLY hard with a socket wrench and a piece of pipe a lot of times.
The rear is now three inches lower.
Is it OK to ride for a day or two with the front and back ends at different heights? I still have to lower the front, but can't get to it for a few days.
