4.5'' front drop and some tire rubbing issues.

My 87' has 2.5'' spindles and 2'' coils up front. I installed this kit last year and haven't drove the truck much since the drop, I was away for Air Force related training.

At that time, I had the front end aligned, the shop used lots of shims. Truck drives straight and all, but I notice the driver side has a tad more positive camber than the passenger side. In fact, this causes some rubbing on the driver side, on the very outer edge of the tire when hitting big bumps. I believe it's hitting the fender lip.

I didn't immediately go back to the shop since I figured maybe the coils had to settle down, but that wasn't the issue. It's definitely alignment related.

Also, the extra positive camber makes the driver side not look as low as the passenger side, has about 3/4'' difference.

The front tires are 235/60/15.

The passenger side has no issues. Think I can remove one shim at a time on the driver side, by myself, until I'm even? Or, think I should have the shop do this?

Re: 4.5'' front drop and some tire rubbing issues.

I'd have the shop do it since you paid them and they didn't do it right. Although, I don't think a tad more positive camber is going to cause a 3/4" height difference.

Re: 4.5'' front drop and some tire rubbing issues.

I take that back, I just measured and it's really more of a 1/4'' difference. Here are some pics of what the issue is.

Passenger Side Above

Driver side below.... notice how it sticks out


Driver side below, once again, sticking out:


Passenger side below, nicely tucked away:

Re: 4.5'' front drop and some tire rubbing issues.

I pulled the 2 front wheels and they have the same backspacing. I swapped them for the heck of it and sure enough no change.

Here are some pics of the fender issue. As you can see, the passenger side fender, I was able to fit 2 nickles and a penny between the fender and hood line. On the driver side, only a penny was able to fit. I'm thinking of using some body washers, and seeing if I match the fender line with the passenger side, if it will be enough to stop the tire issues.

The alignment sheet says my left front camber is 0.5 degrees, right front also 0.5. Caster for the left is 4.0 and right 3.7. Toe for left is 0.20 and right is 0.18.

Re: 4.5'' front drop and some tire rubbing issues.

Well, that was a no-go. Fenders barely moved out after loosening all the bolts. Looks like I will have to take it to the shop and see if they can do anything. Got me worried because I was hoping to run 255s up front.

Re: 4.5'' front drop and some tire rubbing issues.

Take some more measurements of the frame to see if it's bent and take a good look at the cross member. That's a pretty big difference from side to side.
