What was done to your JK this week?

What front seals did you use? They switched through the years and you've got the old style (like Synergy and cheap) then you've got the new Mopar 2 piece style- crazy expensive lately. I ended up finding them for $9 each but then some higher priced shipping through Drivetrain America....guess who bought 4 seals to save on shipping, knowing that I'll have to do the job again, on my jeep or a friend's. I went with the new style because they seem to seal better than the old style (even though I had two sets of the old style in my toolbox).

Thanks! Install videos/directions seem straight forward! No desire to touch the diff outside of fluid changes and have been eyeing the RCV's for a while... The AEV Borah wheels I added last year are shockingly heavy and could be a stressor on the front axle (I can barely get the spare on the back)... Will use this time for a wheel hub/bearing refresh while torn down... Probably going to pass on trusses/sleeves at this point (mixed comments in the forum)... I keep eyeing axle housing upgrades but not running on a lift that extreme or corresponding trails - yet.

I used the standard one piece, I wasn't aware of the new design until now. If these leak I'll try the two piece version. It's really not a difficult job and I won't mind doing it again. These seals might also last until whatever the next axle upgrade might be, so I guess we'll see.
Also, on those seals- I don't know if I've mentioned it lately, but the dealer includes a highly smelly orange RTV to install them to give them a little better fighting chance of holding. The mechanics that do these often have extra tubes in their boxes. My friend brought over a tube and it will stink you out of the garage, but it is watertight (oiltight) as a whale's keister.
The shafts really aren't bad to do at all. We only had to empty the diff to get at the seals. The shafts slide right out after you pop off the brakes and wheel bearings, so all of 7 bolts per side. They come greased and ready to install. I can't say what difference they make on road during normal driving except that the old u-joint must have been worn because the steering has tightened up significantly. I just like to beef up when the opportunity presents itself.

Holy crap - Getting my original hubs off took everything I had. Needed to use the youtube trick for each of the 6 bolts holding the hubs on after giving up on the BFH method. Basically loosen the bolts 10 mm then using sockets and adapters of different lengths and turning the wheel to utilize the steering system like a hydraulic ram! EVERY BOLT! Lots of mud/rust in there - cleaned up as much as I could. Next challenge is getting the new abs wires connected (putting on new hubs as well and new sensors came with). Sure hope the new axles come this week!
Update - Found some brake rub on the pass side brake lines so ordered new Teraflex line anchors (old ones were a little worse for wear) and Teraflex 26" steel braided lines (which are shorter than the lines on it??. Broke off the mounting brake line bolts in the frame - was able to remove and order new retainers and fasteners.
The Bad news - On the previously stated ship date from Morris 4x4 I received a note stating it would be another 3 weeks on the RCV axles! Jeep still up on blocks... Debating on putting all back together then taking all apart again in a few weeks or just letting it sit since not driving much these days...

It's not a cheap solution, but the JKS links have been good to me and they're adjustable to cover if you go up or down in lift. They're also a good backup for the Rubi sway bar when it decides to act up.

+1 - 7.5 years later my JKS links still holding up. On/off in about 30 sec time too can't be beat.

I have some Rock Krawler adjustable endlinks that are.. surviving. The quick disconnects still work well, but the super tight 0000 grease joints are definitely not happy.
