A friend of mine has a 2001 cherokee and had another friend install a rough country lift about 2 months ago. Recently hes had issues with control at high speeds. He described it as " when decending from a bump at 70 75 mph the steering wheel goes crazy and takes all his strength to gain control. And while all this is happening his pedal assembly moves around violently." None of these things happend before the lift was installed which leads him to believe the lift has something to do with it. Whats everyones take on the situation?
