I did my own... . on my back... . in the backyard. Followed the instructions to a tee. Took about 3 hours total. I adjusted the bands at the same time. The BD instructions were very helpful. Others have said it is important to take accurate pressure readings before and after. I did. But there was no adjustments neccesary. It ran real smooth from day one. You will love the improvement, especially when towing.
