Ok this is more of a hypothetical question/"can it be done?" at the moment...I will explain so please bear with me. I have a 2000 Jeep Cherokee Sport 4WD 4.0 inline 6. I have not done any modifications to it. The engine and transmission, both run good and strong. My transfer case is leaking and I know I need new seals at least. Have had some issues with the brakes, which I will explain in later in this post. My step-sister, who is a worthless P.O.S. talked my dad into co-signing for a 2002 Jeep Grand Cherokee 4WD for her, which he is now paying the note on it, and is in another state away from me and my dad, and she claims the engine is shot. What exactly is wrong with it, I'm not sure. She did say in a text that it needs a new water pump cause it always over-heats. Which that there tells me there's a whole lot more wrong with the engine if it is still being driven and allowed to constantly over-heat. Since my dad is paying on it still and it can't be scrapped without a clean title, I was wondering if it were possible to swap out my inline 6 and transmission and put it in the the 2002 grand's body and axles, given they are in decent enough condition???
The brake issues that I mentioned earlier are as follows. I blew the wheel cylinders a couple months ago. We replaced them, and the whole rear system, including the lines. About a month ago, while driving with a full load of steel in the carog area, my front brakes started over-heating and damn near caught on fire while I was driving. It was determined that the caliper failed and was covered under warranty, so we replaced all the front including the rubber lines. Couldn't get the pressure to build back up at all, and was hearing a sucking sound from the master. So, replaced the master cylinder. We would get pressure when bleeding them at the back, but as soon as we would move to the front, and open the first bleeder valve, I would lose all pedal pressure and will not build back up. So we have now got a proportioning vavle from Mopar. Haven't had the time to put it on yet, but am really hoping that fixes the brakes on her so I can at least have that one on the road again.
Any advice is welcome. I am not exactly a novice around cars, and my other half has been around cars all his life, so we know our way around them. :-)
Thanks in advance to anyone who offers advice.
