I have searched and searched for some answers but cannot find them.

1- Since lifting my jeep with the Teraflex 2.5" coil lift and installing 35" tires my front tires seem to be wearing on the inside edges? the alignment was fine and only recently seems to be pulling slightly to the right but when there was not pulling to the right they were still wearing on the inside. After installing my lift I did the alignment myself per the instructions on Project JK. and all seemed great till now. Anyone have any ideas what may be going on?

2- Also lately my jeep seems to be making a loud squeaking when I am backing up. does not make the noise when going forward no matter the speed I am going.. Any ideas and what could be causing this?

Jeep seems to be running great otherwise and I love the lift and the ride..

Thanks so much for any impute..
