new motor mounts? swap 2.4 to 4.0

I get that I need to change the mounts in swapping the 4.0 into my 97 2.5 TJ but do they require welding? Where can I buy them?

Thanks for the tip & the welcome. I went to Advanced adaptors and looked around some and didn't find the mounts. I guess I'll have to look harder. I also noted on another thread a post w/ mount part #'s but I wasn't clear where the mounts came from in that post.

I have some other questions such as will the bell housing from the 94 4.0 Cherokee meet up w/ my 97 2.5 TJ trans? Or should I try to put the Cherokee transmission and transfer case in there and if so what about the driveshafts?

Here would be a good place for you to start.The AW4 trans would be a good swap because of the overdrive! http://www.stu-offroad.com/engine.asp

Thanks, I will. I've been looking further into the matter and it seems that I should pull the TJ 2.5 transmission & transfer case out as well and put in the AX-15 w/ transfer case that came w/ the 94-96 Cherokee. Better transmission I understand. Still concerned about the driveshafts though.

Found the motor mounts at Browndogs but wish there was a bolt on arrangement as I don't have a welder and hate to haul it to weld the mounts.

A little concerned about the change in transmission length and transfer case too.

With the mechanical portion out of the way I still have to deal w/ the accessories - AC radiator and so on and then the electrical.

One thing at a time...

The transmission behind your 2.5 will not bolt up to a 4.0 I6, so a tranny swap will be required rather than optional.

You could have a welder come to you to do the motor mounts.

Thanks for the reply. Yea, at first I thought it would be easyer to change the bellhousing at the trans if possible and mate it up but I guess not. Thats ok though cuz if the AX-15 is a better piece I have it and might as well use it. When I stripped the Cherokee I thought it might come in handy even if only to sell it to recoup costs.

What about the drive shafts? Isn't the lengths w/ the new arrangement gonna be different?

The required driveshaft lengths after the swap will end up being real close to what they were previously.

I would not try to plan the motor location around the driveshaft lengths.

Ok thats great. Thanks again. I guess I'll know whether to use the Cherokee's shafts or the TJ's shafts when I get there.

And bringing Mohomed to the mountain, the welder to the jeep, makes good sense too provided I can find the welder. I do know of a couple of shops around here.

What about removing the front clip to do this work does that make sense to you?

Yes, I would pull the fenders and grill.

It does not take too long.
