Hey just wondering if the front of the 4R was lower to begin with or do they normally sag after the years pile on?
I have a 2005 sport edition and I measured my front and rear heights before I installed my toytec ultimate lift and I remember the front being a couple of inches lower than the rear. Unless your off more than that I wouldn't worry about it.
Both. Front is lower from start, because of the added weight of the engine. But All coil springs will begin to sag at some point.
