Im 100% Polish living in Chicago ;P
what is the CPS responsible for ?
I had a little argue with the steelership today & had to pay $200
for a diagnosis + Fuel pressure TEST, Fuel DRAIN & $20 worth of new fuel and another DRB TEST (no misfire codes )
Result--> Needs NEW PCM ,ONLY NEW NO GUARANTY or possibility of returning if doesnt help $1000
they said that they will not do any more testing b/c they dont need to :O
(I was hoping for a engine compression check & injector noid test)
Found a place that says that they will check my ECU-PCM-CPU for $40
reprogram it for $90 and if its bad a used reprogramed for $250
SADLY Im not able to any work on the car myself b/c of where I live
I know previous owner verry well, he left me the car after getting 4th DUI
befor leaving he told me that there was a lot of work done on a car like
1 of coil packs is new, spark plugs, wires, new exhaused, shocks, TMC reseted, ETC
but I dont really know what exaclly was accually DONE and checked !!
no receipts, no phone numbers
so I cant really relay on what he said :/
what do you think ? what should I do ?

anyway if you need a PCM go to pick one at the JY, you can easily do the work your own, the computer is under the hood.

I may be missing something, cuz I just joined, but how do I post a question??? I may be old, but I've owned quite a few Jeeps from a 1951 M1B (Still have it) to a 2004 Grand Cherokee - The older ones I've a bit of knowledge to share, but these new fangled ones with OBD II code readers and the like are a little beyond me - Could use some help!!

hammer and flat screwdriver make a hole on the seal face and pull it out. Tap the new seal in place with either a wrench extention or something that fits around the shaft.

front dana 44 hubs?????
So I've decided to "go big or go home", and do a full with axle swap, but I've already found myself lost with these things called " manual locking hubs", not really an XJ thing lol. So what I've got is a 78' ford dana 44, and I've changed the outers to the heavy duty, external mount hubs, but what my question is, is what spline hubs do I need with the heavy duty outers and are they compatible with what I already have?????? Please help!!
