how would i find out if i have a D35 or D44 axle? its a 2005 Jeep wrangler Sport with 26000 miles on it. They are also saying that my 4" skyjacker lift is putting the pinion at a steep angle causing that to leak too. I really have no mechanic training for the exception of changing a tire and changing my oil and oil filters. So any info would help a lot. Thanks for you replies.

Your automatic transmission is usually incredibly reliable unless it's abused. Usual methods of abuse are by heat, contaminating the fluid, or by neglect of service.
Excessive heat is often caused by towing, aggressive driving especially offroad or on mountainous roads, and long periods in low range (high rpm/low road speed).
Fluid contamination is usually water (driving too deep) or particulates, which can come from poor cleanliness when servicing or wear particles from worn internal components, which usually come from a lack of servicing or just general wear and tear due to high mileage.
Servicing is very important, but also very easy. It consists of dropping the pan, draining the fluid, replacing the filter, adjusting the front and rear bands (very important and often overlooked), cleaning and replacing the pan, then filling with fresh fluid.
Does any of the above apply?

If it's a D35 the differential housing will look like this:
and if it's a D44 it will look like this:
These of course are rear axles. Your front one will be a D30, and look like this:
With regard to your 4" Skyjacker lift, if no other mods have been done to correct the driveshaft angle, then they're most probably correct about the pinion housing leak. You can also expect premature failure of the universal joints.
Few major modifications come without side effects, one of which is that they can put stress on related components, and another is that consequent warranty claims connected to the modified components can be denied.

Success at last..... After changing the complete ignition system, crankshaft position sensor, catalytic converter, fuel pump etc. and getting NO codes, I decided to look into the exhaust manifold a little closer. In order to see if it was causing the O2 sensor to get false readings, I took the O2 out of the equation by unplugging it. While it won't be good for fuel economy, it did stop the problem. I am ordering a new manifold to stop the leak and will probably install a new O2 sensor. Don't know if it would be your same problem, but the problem seems to be resolved on mine. Let me know what you find on yours.

Thanks for you help Mac24, is it a hard process to change axle seals myself? if so is there a specific reference or manual you could suggest for me?

It's not hard, though it will require the use of a press. As I mentioned before, you should change the bearings at the same time. You can remove the axle half shafts yourself, then take them to a machine shop, a local mechanic, or even NAPA, to have the old bearings removed and new ones pressed on.
The best reference is the Factory Service Manual (FSM) which costs about $100 (or two tanks of gas). Alternatively, you can have twelve months unlimited access to the FSM for $25 here at: AllData

No, not really. I did tow a really heavy generator one time (I'm guessing 3 or 4000lbs), but that was only for 20 miles or so, and I was very easy on it, and the Jeep was brand new.
I've serviced the transmission, and although I'm not sure what the manual says, once under 49k should be enough.
Wonder if the bands were adjusted?

Hi, just posting to let you know the outcome of mine. This is going to be of NO help to you at all. I decided to sell the Jeep while it was still worth a good bit of money. I was trying to wait until it got fixed to sell it, but the Jeep dealership took six days to get the CAM sensor in. By then, I had found a car that I wanted, so the mechanic never did pick up the part, never did fix it, and I took it to the dealership to sell it today without it being fixed. Soooooo...obviously I don't know how it will run anymore.
I can tell you it's a heartbreaker to give up your Jeep, but ours was going to start costing us more money than I wanted to get into with the roof leaking, potential rust issues, the cracked manifold that will eventually need to be fixed, etc.
Anyway, best of luck with yours. Sorry I couldn't be of any more help with this.

Took the jeep to the 2nd dealership and they said it was normal engine noise caused by the fuel injectors. Does this sound right to anybody?

While the injectors do make a tapping noise, I can't tell from here if that's actually what you're hearing.
If the noise suddenly appeared, or if other Jeeps don't make it, then it's not normal and needs to be addressed.
