Got under the Jeep today to do a little maintenance.
Found a pretty good leak on right side of front axle. This is only 10K miles after regearing and lift.
Shouldn't the seals have lasted longer? Done by a reputable shop.
Well since I have to get the seals replaced might as well go ahead with the True Trac up front. Labor and parts will already be covered except for the True Trac.
Anyone have any experience running one up front?
I have one in the rear and works great.

 

you dont need to go through the process of setting gears up again to replace seals. Pull the carrier and keep all shims accounted for and in order. Replace seals and drop everything back in the order in which they came out.

 

D_ is correct. Replacing the existing carrier with a TrueTrac will require resetting the gear alignment. Since you are reusing gears, only carrier shims (not pinion) will need to be adjusted. Changing the carrier will also require pressing the old bearings off the existing carrier and onto the TrueTrac which might cause damage to the bearings if not done carefully.

If the seal is leaking already it might be because:
1) differential was overfilled. Jeep differentials are designed so oil is splashed onto bearing. Bearings are not to be completely submerged.
2) seal was damaged during axle insertion (the plastic "Front Axle Shaft Guide" helps prevent this)
3) seal was not lubricated before axle insertion. I grease the seal so it starts life lubricated.
4) dirt from within the axle tube got on the axle during insertion and ended up between the shaft and seal. (once again, "Front Axle Shaft Guide" helps prevent this.)

 

I have Truetracs front and rear and they are a lady on the streets and a beast off road even in the Carolina mountains red clay with OEM Sahara Wheels and tires.

 

Someone noted pressing the old bearings off the old carrier. Do yourself a favor and go ahead and get a master install kit. You can get a Motive install kit for around 100 bucks if you look around. More times than not the bearings get damaged when they are attempted to be removed from the old carrier. I know the shops around here won't even consider it. They require master install kits.

As for the truetracs front and rear, that is my current set up. I have a 2014 Sahara with 4.56 gears and F/R truetracs. I have noticed no difference in road manners and no additional noises or clanks. Off-road, they have locked up every time and work great. In fact, they work so well, i'm questioning why I ever went with Detroit lockers in past applications. When I get to my other computer, i'll load up a video of me climbing a ledge at Uwharrie on Rocky Mountain loop. You can see all 4 tires locking up and slowing churning me up the ledge. Despite the wet red clay and rocks, I had no need for the skinny peddle. I contribute part of that to my tire selection, which they have blown my mind thus far. But my ability to slowing crawl up the ledge safely and controlled had everything to do with the TT's and gears. Give me an hour or two on the video, but i'll get it in there today if I can figure it out.

 

As promised.

Thanks for the vid.
Definitely going to put it in.
