Some questions....
Just wondering what you guys think of not being able to service the front suspension. In other words, there are no grease zerk fittings to replenish grease for the ball joints and steering linkage. On my 1998 ZJ, I had 6 zerk fittings so I was able to always pump synthetic grease in the steering linkage every other oil change. Any possibility of the ball joints drying out, since the 2011 GC is not servicable? Also, I hate the fact that there is no dipstick for the transmission. Lastly, how are the front and rear differentials on the 2011 GC's? I have the Laredo E with the Quadra Drive I - fully atomatic. The reason why I ask is, as most of you know, in the past GC models, the Dana diffs became noisy, especially the rear diffs, after certain many miles and needed to be repaired. I myself needed to replace the carrier and pinion bearings 3 times in the 13 years I had my 98 ZJ with the Dana 30 and 35 diffs. I'm assumming they are much better now and Jeep has since resolved these issues.

Re: the rear diff - Your '98 ZJ was a solid axle D44 with an aluminum center section. I doubt the IRS diff in the WK2 will see the stresses that the ZJ diff did.

Actually it was an open diff Dana 35 rear on my 98 Inlne 6. I agree, the 2011 diffs probably won't see as much stress. Any idea what the name of my rear diff on the 2011 is? Again, I have the QD I if that helps to identify the diffs, front and rear. Thanks! Any comments on the suspension, specifically no zerk fittings? Just wondering.

It's common to have no zerks fittings on cars now. Didn't have any on my 02 gc or 06 commander. Even the universal joints are sealed. Might be due to improved lubricants. (better grease sealed in there) or more probably cost cutting since each of those fittings cost money. The grease fittings also allow a method for a sloppy mechanic to force dirt and sand into the part because they don't take the time to clean the fitting off. That can lead to premature failure as well. I have over a 115,000 (and a lot of these are hard miles, towing, off-road, etc) on my 02 jeep and so far the only part that used to have a zerk fitting and had to be replaced was the rear 2 universal joints. But guess whAt the replacement ujoints I bought at Advance Auto did have fittings but I would not worry about it too much.

Re: Some questions....
the WK's they have been producing since 05 have ZERO ZERKS. one or two of them are still around and the wheels havent fallen off yet :lol:

I dont like the fact that there are no zerks but thats how it is. if it is that bothersome Im sure you could drill and tapp a batch of zerks in yourself. or get one of those hypodermic grease needles and fill the boots up yourself once a year.
