front driveshaft hitting exhaust

My tj's front driveshaft yoke is hitting my lower exhaust pipe where it goes around the front of the oil pan. Its only when my suspension flexes off road. It has caused a golf ball size dent in the exhaust pipe and is about 1/2 in deep. What would yall reccomend as the best fix? just some info that might be relevant to the problem, it has a tcase drop, 4 in lift, d30 front axle, stock exhaust and driveshaft, and has the sway bar connected at all times

Lowering the transfer case/transmission skid plate also lowers the catalytic converter hanger that's attached to the transmission mount. This causes the front "Y" pipe to swing closer to the driveshaft...

sounds like you have the clearance you need already? how much more will/can the driveshaft contact the exhaust? is it even necessary to change anything?

basically you are trying to prevent the axle from coming up too far. You need to add some bumpstops, whos job is to limit uptravel. there are many options for bumpstops, from expensive machined aluminum pucks to hockey pucks and everything in between. from a few dollars to +$100.

you could also extend the catalytic converter hanger to push it back up the 1" its dropped due to the t-case lowering.

so do you want to do exhaust work or suspension work.
