I just installed a 2" coil lift on my 1989 Sidekick. Went on a day long desert run yesterday. After about 2 hours I started to hear a rubbing noise from the front that would only last 1 second or 2. Only heard this noise about 5 times all day. Had been driving all week in 2wd and no noise. Now in 4wd is when the noise started. I need to replace the boots but noticed the price for rebuilt shafts are not much more. Plus I am afraid if I replace the boots, then the joints will go out. But there is no play in the shafts. So I am not sure what to do. Any suggestions? Thanks, John
