Wow. This really bums me out as I am about to replace my front pads and rotors with 60K on the vehicle. The pads on the outside are fine, but the pads on the inside have worn disproportionately and the rotors are corroded except for a small area where they are smooth from contact. I wish i had pictures, its hard to explain.

60K is not bad for factory brakes. I had Hondas for years; good cars but they put the cheapest rotors and pads on them that would warp at 20K. I replaced with Raybestos rotors and ceramic pads that would go for 60-80K+. Get them from Rock Auto.

That said, if your wear is uneven I bet you have sticky calipers, so make sure the caliper pins are cleaned and lubed. Maybe change the boots on the pins, too.

Looks like QL system is still a problem here. $2000 for the compressor? Kind of regret it now.

Re: WK2: 100k mile 'review'

120k on original hemi plugs? Wow, I was thinking about doing mine this year as I just hit 70k on original. I checked a few last year and they were still in great shape. Still runs fine with no mis fire so I think I'll hold out a little longer.

My last car called for a plug change at 105k, i was trying to be proactive and changed them at 85k what a waste it was, the plugs were in great condition and gap was fine. They could have gone much longer. Every engine can be different but im not touching these ones early after that last experiance.

I will offer this advice, when changing 100K plugs, buy the closest to OEM spec as you can, or factory replacements. If it calls for $14 Iridium plugs, don't buy the $3 Platinum plugs or you'll be doing it again in 25K miles! A real pain on modern V6's when you have to remove the intake manifold and lots of other hardware to get to three of the plugs. I learned this the hard way...

The 2011 hemi plugs are copper not irridium, manual calls out for change at 30k. If memory serves, the hemi did not get irridium (ie 100k) plugs until 2015 or 2016. Going longer seems to affect MDS for most people and causes a noticeable drop in mpg. I just changed out the plugs in my 2011 RAM (just hit 30k miles) and saw a noticeable uptick in mileage. For $60 in plugs and a Saturday afternoon I would go ahead change them. Sometimes plugs that look good on the outside can be breaking down on the inside.

You don't have to pull the intake off, but the drivers side will utilize all of your wobble extensions and still scrape your knuckles a little. I have both a GC and a RAM both with the hemi, ironically the GC is quite a bit easier to do the plugs on. In the RAM the engine seems to sit back further, and the master cylinder is right in the way. The GC is easier to get into all of the plug locations.

+1 on always buying the OEM plugs. A quick search on forums will find you a laundry list of issues from guys who put platinum or irridium plugs in the hemi's. The <2014-ish hemi's require a copper plug, and from what I read when I did mine they only seem to like the NGK OEM plug and otherwise tend to throw codes for the MDS system.

Thanks for the info. Glad the hemi plugs are driveway workable. The 2014 GCs got the irridium plugs so no changing these to 100k fortunately. The 2014 GC owners manual had 8 editions and they didnt make the correction from 30k to 100k plugs until the 4th or 5th or something like that. So there could be a lot of people out there changing them at 30k on their 2014 GCs that dont need to.

Consider yourself lucky that yours have lasted so long. Anyone who's owned any of the early model year GC's can tell you how piss poor their rotors were for wearing and warping within 8-10K miles or less of new. Chrysler denied the problem from 93-02 before they finally fixed them.

The original plugs on my 2011 5.7 are not copper. They're ngk nickel. Which is why they're lasting way longer than 30k. I pulled one out to check for the same part # as the new factory replacement ngk I got. ImageUploadedByJeepGarage1464787958.749927.jpg
