I just had my lock-right installed in my rear diff. this week-end and these are my observations. It took me about 15 minutes to get used to driving it on the street, the clicking doesn't really bother me and the difference in handling on the street is minimal. Now to the good stuff, I went to the dunes this week-end and the difference is amazing, I can now cruise up dunes that I had problems getting up before. I was driving behind a guy in a Cherokee who was hard on the gas to make it through and I just cruised right by him. Best $260 dlls. I spent in a long time!
