exhaust manifold

my exhaust manifold has cracked and is in need of replacement. i've been quoted about 400 for the part, and 200 or so for the labor. i'm looking for suggestions on where i could find the part online (hopefully a cheaper alternative) and how much of a pain it would be to do myself. thanks for any input.

Thats been a problem with the Jeeps, cracked manifolds. Well I'd first look for a junkyard and maybe you can get one there. Then go searched through the web, but STAY AWAY from the dealership. They will hang upside-down .

I have replaced a number of them on the 4.0L, all seam to crack ing the same area. Usually around the collector or rear cylinder pipes. Cracking is a real problem.
I would either go to a Borla or Banks header. If they are out of you price range. I would go through the dealer for the "improved" version. You can look around on the web and get a lower than retail price on them. They can still crack, but it was susposed to be somewhat corrected. I have installed a few aftermarket versions, I did not like them at all.. and will not use them again.
While your in there replace the fuel injector seals and clean the bore around the injector. I have found them to get coked up .
