I have a new 2014 JK Rubicon Unlimited. At the 600 mile mark I noticed the front end on the passenger side was low.
On measuring top of wheel well to cement floor (through the axis of the front axle) driver side measured 36.5" while pass side measured 35.5". When I measured from the floor to the top if each mirror (vertically up from the rear contour (trailing edge) of the plastic fender, I got a difference of 11/16ths (45" driver side; 44-5/16ths pass side). I then measured the front end of the rock rails to the floor and got 17.5" pass side and 18.5" driver side. All measurements were taken with tire pressures all within 1lb of each other on a clean garage cement floor.
The dealer has now replaced shocks and springs on both sides of the frontend. It made no difference.
While this symptom could be cured by adding a 3/4" levelling kit spacer to just to passenger side it seems to me that would be curing the symptom but not the root cause of the problem. I suspect too that frontend geometry will be affected and have to be re-aligned. And I don't know if this will accelerate frontend parts wear. The vehicle handles well at present.
Any ideas welcome. Would sure like to fix this. My research on this and other forums shows some discussion but no real fix.......??? H-E-L-P please.
