I had the 6.5" BDS lift installed on my 2011 LML last weekend and have driven it every day since. Today when I went out to get in my truck at lunch I noticed a quarter size leak on the ground. I climbed under the truck and it looks like the axle tube on the passenger side is leaking Diff fluid. Is this coincidental or did my local shop do something to make the seal start leaking?? Should I push to have my 4X4 shop fix this or take it to the dealer.
