Rear tire rub...thoughts??

I just replaced the shocks on my 98 Sport, and I now have a new issue. Quite frequently, it seems that the outer edge of my rear tires rub the flares. It does not seem to be that big a deal, other than the melted plastic, but I don't like the noise. I run 15x7 Cragar 342s, and 235/75 tires. Any suggestions from the wisdom of the XJ community, as always, are much appreciated

Rob

Does your rear leaf springs sag? Sounds to me like your leaf springs are shot and when you hit a bump its causing your tire to rub.

Leaf springs are solid; bump stops appear to be crumbling. I'll have to pick up a pair tomorrow and put them in. Hopefully, that will take care of the issue.

Measure your rear from center of rim to bottom edge of flare. If it measures less than 17 inches, your "solid" leaf springs are flat. Replacing bumpstops will accomplish nothing toward fixing your issue.

With a good set of leaf springs I don't see your tire rubbing that much with just bad bump stops. Especially on the road. Unless you hit something like a speed bump at a fairly fast speed I doubt your bump stops touch on a everyday basis. Unless of course your springs are bad. Are they U shaped or flat? If are not holding an arch then they probably allowed your bump stops to hit more freq than usual causing them to go bad. In that case replacing the bump stops wouldnt be any good because they will eventually just wear out again.

I my jeep is only 2 years newer than yours and I have 165k on my factory bumps and they look fine. My point is your problem isnt just with the bump stops

Did this problem just start after replacing the shocks? Did you put different rims on when you did the shocks?

I think what maddzz is getting at is backspacing of the rims. I had the same rims they are the correct spacing.

Your rear would have to be compressed a lot for the bump stops to come into play. Nor do I believe you would traveling fast enough to melt a flare with rear compressed enough to have the bump stops come in to play... unless of course you are trying to climb a obstacle and are using the skinny pedal.

As others have noted...I don't think ig it your bumpstops (although I wouldn't be surprised if they needed replacing also)... but rather weak/flat springs. Most XJs with stock leafs have such issues.

Flat springs with increased tire size means the rubbing and melting flare. Perhaps your shocks were rated for a higher weight... which may have give just enough help to your spring to prevent the now rubbing.

They are Monroe shocks, better than OEM. I have 16.25" from the center of my hub to my flare's lower center, sooooo, it looks like I am in the market for some reasonably priced leaf springs. Any suggestions for a good vendor (other than Quadratec--too pricey!!)? Thanks.

OK. Installed Quadratec HD leaf spring packs and Skyjacker Nitros. All better. For now Thanks for the feedback. As always, it is appreciated.

Mine was sagging down to 16" in the rear before I added the HD leafs from quadratec, and I also had 235 tires but they didn't rub. How much lift did you get from the HD leafs?

Between the super-stiff HD leaf packs and the super-stiff Nitros, I am at 18.25" from hub-center to flare bottom edge. I'd say I gained 2 inches from where I was. What a difference in the ride. The springs are great, but the Skyjacker shocks are amazing...
