New questions

[dana44]

Hey, brothers and Jeepers!
I have some more questions for you guys. I'm gonna change the transmission mount on my Cherokee (AW4), where could I buy thease online? Is there any aftermarket mounts that are better than the OEM parts I would normaly buy? Is there someone out there that makes dual exhaust for the 4.0L? Where to buy if they exist? (larger than stock exhaust systems are illegal in Norway, but dual is not!) Whitch free wheeling hub is the best? WARN or MileMarker? How does the AirLift perform on the Cherokee? Anyone with experience out there? Where to buy online?
Thanks in advance!

Most folks recommend swapping both motor mounts and the tranny mount at the same time...MORE Bombproof motor mounts seem to be the (expensive) favorite, then OEM or aftermarlet rubber. I got rubber mounts from Advance Auto - a national chain store- and these have held up fine so far. Polyurethane mounts will transmit more vibes than rubber.

I know no one who makes true duals for an XJ 4.0 (the exh manifold is 6>1 (or 3>2>1) but seeing how your country is restrictive as far as mods goes, I'd stick with OEM-spec 2.25"/57.2mm stuff. If allowed, a higher flow cat and muffler may 'sound' and flow better. I run OEM replacement stuff...no cool-points for sound, but my stuff gets hammered on the trail and I like destroying cheap stuff vs expensive stuff.

For hubs (and alloy axleshafts) I'd have to vote WARN. Bear in mind that the 5 on 4.5" (114mm) hubs are lighter duty than the 'Premium' 5 on 5.5" (140mm) Both will require rotor mods (or modded CJ rotors for the latter) I don't have any experience with Warn hubs/axles, have had good luck with OEM + Spicer 5-297 shafts and a Lockright front locker)

I looked in my records and the OEM part numbers for the new mounts are:

Engine - 52019201
transmission - 52002334

You will have to buy two of the engine mounts and we are lucky on XJs you use the same mount of both sides of the engine.

If you change the passenger side mount you will have to remove the oil filter mount to get the through bolt out. You will need one of each of these O rings to reassemble the oil filter mount: 33002970, 33002971, and 33002972.

I do recommend you get a subscription to alldatadiy.com. There is a technical service bulletin where chrysler revised the through bolt torque for the mount. Alldata and the factory manual is the only place I found the torque value and the TSB was the only place I found the revised value - 48 ft-lb (65 N-m).

I have had good results with the OEM mounts and someday plan on changing them again. I agree on the change all 3 mounts at the same time. My Jeep dealer told me that how they do it because they have learned if you change one then the remaining ones fail faster, so renew and have them all wear out at the same rate.

You can look at a US website like parts.com and find jeep dealers that sell items at a reduced cost, not sure about international shipping.
