2004 Wrangler. Advice before I buy!

2004. 70k. Auto. 4.0L

Took it to my mechanic. 2 small leaks:
1. Oil Valve Gasket
2. Rear Differential Seal

It also needs new shocks, but that can be down the line. Otherwise, everything else on this Jeep is great. Interior is in great shape. Not a dent or scratch (that I noticed). Drives great. Shifts well. Good pickup.

Should I be concerned? Could these leaks lead to a major problem? Mechanic says he can fix, but I don't want a constant problem that will lead to something much larger.

Thanks!

Looks good, I wouldn't be concerned with those two small leaks. One word of advice... if you see that Jeep as a future lifted Jeep running big tires and perhaps lockers, I would look to see what rear axle it has first.

Jeep Wranglers came with one of two rear axles... the standard Dana 35c which is ok with tires up to about 33" but no locker. The Dana 35c is actually known to break with 33" and even smaller if you are a little too agressive offroad. But for most people and mild offroading, the rear Dana 35 axle is fine.

The optional extra-cost Dana 44 rear axle some Jeeps came with is far stronger and is up to nearly whatever you can throw at it including 35" tires and a locker. It's a highly desireable axle that most Jeepers who like to offroad either wished they had known about in the beginning or later upgrade to at a significant cost.

The two below photos will allow you to quickly identify which axle you have. A quick way to tell is the Dana 35c on the right has a perfectly oval differential cover with a snap-in black plastic lubricant fill hole cover.

The Dana 44 on the left is more stop sign shaped with a threaded steel plug in its differential cover.

2. Rear Differential Seal

1. Do you mean the valve cover gasket?
2. Pinion seal or the cover seal?

I would look the Jeep over really well. If it looks like it was run in deep mud or water, I'd pass. An oil leak or two isn't as bad. Good luck.

Thanks man. I don't have the Jeep with me, but I can check if I end up buying. I might get it lifted one day, but as of now I only plan on light off roading. Nothing too heavy.

1- Valve cover gasket, yea. As long as it can be fixed and not turn into anything serious (head gasket?) I won't worry.
2- Not sure. I just remember the mechanic saying Rear Differential seal.

The owner (original) said he's never taken it heavy off-roading. Just some sand and dirt.
