DPF Removal with truck on the ground?

Is this possible? If so, how hard? Has anyone done it? Keep in mind that my truck is stock ride height and still has the stock Goodyear Wrangler AT/S. Also, are there any tips or tricks I should know before I do this?

Thank You

I did mine by myself on the ground 2 weeks ago. Easy to do. Under 2 hours. I first ran a ratchet strap across the bottom of the truck, underneath the dpf, to support the dpf and too keep it from falling on me. I then disconnected all sensors. I unbolted all the hangers from the frame. Loosened the clamp holding the dpf into the rear part of the exhaust. Wrapped a ratchet strap around the rear axle and the front part of the muffler and ratcheted it down until the dpf seperated from the exhaust pipe. Then I loosened the down pipe flange. Now everything is loose. Then I pushed the whole assembly towards the driver side to let the hanger bolts clear the frame. Now the whole assembly is totally disconnected. Slowly lower the assembly by loosening the ratchet strap suspened across bottom of truck. Take off ratchet strap around muffler and rear axle.

Now take the hanger that you need to transfer to the dpf/cat and transfer it. Then hook it all up, install the dpf off tunes and enjoy the $%^& out of your truck.

See that was simple.

Not hard at all. Just tedious and cumbersome.

I did mine on the ground last week.

x3 a few weeks ago. I'm not a mechanic by any means and it went just fine. I could go do it again just fine--only if I had to though.

Take out your spare tire and jack up on your receiver hitch to get all the load off the rear suspension, then unclamp the rear section of the exhaust and pull out from the back. Then you can remove the rest in one piece by unhooking the sensors and unbolting it from the downpipe and unbolting the hangers.

Most people do them with the truck on the ground, there is plenty of clearance to work under there.

I just broke out my sawzall and had it done in less then an hour. But if you want to do it the long way around 2 hours seems about right.

Just finished installing mine. Apparently the nuts from the dp to the flange to the doc are welded to the flange (I didn't know); and the bolts that are attached to these (2) welded nuts...1 is easy to get off (13mm) but the one up top...is a SOB to get off. I didn't bother removing the crossmember/skid plate, I used it to catch the DPF/DOC pipe and then just slide it off once all the hangers were undone (another PITA). But it's all done and the 275hp tune is loaded.
