exhaust hits front driveshaft

Hey everyone. I bought a 2001 wrangler 4.0 about a month ago. It had a 3-4" lift on it already. The exhaust hits the front driveshaft universal when you take off, but no other time even when off road. I changed both motor mounts, but no change. Possible something was left out when the lift was installed? Exhaust is stock. Don't know brand but has a superlift decal (not much help i know).. Any ideas?

You will have to do a little exhaust work in order to make clearance. If you can't do it then take it to a muffler shop.

Same problem occurred with my TJ with only a 2 inch lift.
After replacing the headers and exhaust problem went away.

My YJ also starting doing the same thing come to find out where the Exhaust header connects to the down pipe, the coupler was loose. I ended up repositioning the exhaust and re tightening the the couple problem solved.

Do you have an adjustable front track bar?...

Very simple fix. Adjust the exhaust pipe a little.
Adjusting tool:

For the exhaust pipe, not so much for the driveshaft.

No, track bar is solid, would getting an adjustable one be an option, seems to have alot of wobble when taking off to.

Check to see if your differential is centered under the Jeep, carpenters square from a fixed point on each side of the diff to a spot on the frame.
