Ok so I found time tonight to get the new mounts in. Wasn't as bad as I was expecting although I did have to fight a few bolts to get the mounts to line up but I'm very pleased with the final results.

Pic of toasted driverside mount it just fell out when I unbolted it.



just used a sawzall to cut the metal band out and knocked the rubber out. It popped right out.

Then I used good grease to lube it up and used my big freakin bench vise to squeeze those babies in there it took a few tries but wasnt very hard. no pics since my batt died on my phone.

Once pressed in it took a little finesse to massage them in but all in all went very smoothly. It took me roughly two hours to do this.


Then I proceeded to remove the transmission mount first I unbolted it from the skid then I jacked it up and braced it. then I removed the skid and simply unbolted the old rubber mount and bolted the poly one in its place and then reversed theprocess. It really only took me about a half hour to do.

I'm using the stock ax15 transmission so I just used the stock wrangler skid plate. I really would like to go with belly up skid to get it flatter but it just wasn't in the budget this time. Maybe when I switch to an automatic 727.
I drove the jeep to work again today and it was a huge difference in the way it performed didn't think poly motor mounts would help this much but it idles smoother now No more shaking on take offs, it doesn't shutter it just halls *** now! Its a whole new jeep again!! It doesn't buck and jump while turning into parking spaces and idling around turns. I can feel a little more vibration at higher rpms but its not bad at all. I drove it to the dealership my father-in-law works at and we hooked it up to the motis again and its code free and running awesome. Couldn't be happier! !

Sweet. I just put some new Brown Dog's on my 4.0L. I didn't have time to test drive but my OEM ones were toast. The metal sleeves just slid out.

Yes they are so nice its just to bad I keep having issues with keeping it running. I think maybe my coil is bad? when it gets hot it surges while cruising and idles rough like its flooding after a drive down the highway, but let it sit for a few hours and its ok. It rips on the highway I never thought I could accelerate up to 85 in 5th gear with ease headwinds are not a problem anymore.

Maybe check the coil primary and secondary resistance when it's cold and then hot after it shows symptoms?

It sounds like a sensor causing that issue but that's a guess.

Yes I checked both of them this afternoon both cold and hot (used my wifes blow dryer) and the resistance was within spec. I've had my fuel pressure gauge on the fuel rail all day and its okay only dropped 10psi in like 8 hrs so I dont think I have a leaky injector.

I also tested my map sensor and it checked out ok too. Its getting good ground and has 5 volts to it. The manual says that with no vac it should read 4.5-5v. In my test with no vacuum its at 3.9 volts?? when I applied vacuum to it (used my mouth) it drops to at 1.6. which is what its suppose to do. So I changed out the tps for the original Holley one to see if it changes anything.

Picked up an idle air control valve. more as a preventive maintenance item I really think its sticking and causing my stall when I come to a stop after driving on the highway

Well replacing the iac definitely smoothed out the idle even more and lowered it a little, it doesn't sound like its camed lol. Anyways need to take it out on the highway to test it out. The instructions say to do that and get it above 40 miles an hour to get the ecm to calibrate it right so we shall see.

So drove it about 40 miles tonight both highway and in town not once did it surge while cruising and when I came to a stop it went to idle woooohooo!! It seems to have worked. I can't smell gas after I shut it down anymore either which would permeate my garage when I got home. Time will tell though I plan to drive it a bunch this week.

Smooth as glass at 82 mph. With the 4.2 top speed was 74 downhill with a tailwind in 4th gear lol.


I have logged 202 miles on it since the iac replacement and not a single hiccup and I'm getting 18 miles to the gallon. Not too shabby!!

Dont think I can go that fast, cracked manifold is sapping the power pretty bad. Kind of jealous. Then again the highest speed limit is 70 around here
