I have a stock 98, but the real is not balance, is about almost 3 inchs different on both side. The front seem fine, what could it be? left side lower the right side, whats the stock high on both side?
I am not following your question. What do you mean by "Real"? Do you have AHC? Need more info on your rig.
BTW, There is not a definitive answer for stock height. There are too many variables that will affect it and it will be different from vehicle to vehicle. If you look into the front wheel alignment section of the service manual (if you dont have one, look in the FAQ for a link to the 2004 PDF), It gives some variables for vehicle heights and diagrams of measuring points.
Adjustment from there on will depend on if your vehicle is AHC or not.
Hey take a look up in there and make sure both sides look like they are seated well. look around and see if anything look different from one side to the other. I dont have experience with AHC so I am not sure if it would affect the rear. Perhaps someone else that knows can help. Good Luck!
So you have measured hub to fender distance, and have a 3" difference from one side to the other? That is a huge amount. Has to be a broken rear spring or something very out of place back there.
If you haven't actually measured both sides, go do that. Measure from the center of the hub straight up to the fender, and record the number you get for both sides. Post a picture of the rear of your cruiser too, if you can (looking straight at the back from about 20 feet away so we can see the "lean" in the stance). That would be helpful.
