Random splatter/ spray around transfer case

So today was happy 5,000 mile day and time for an oil change.... But when I slid under the jeep I noticed there was dark colored spray/ splatter all over the heat shield around my transfer case....

My 2010 jku has almost 60,000 miles on it and I have done every oil change since 20,000 and idk if this is just the first time I have seen it or if its new....

Let me know what you guys think, is it normal or not , or what the deal is

Thanks,
Matt

If you look at your picture you can see where it is coming from.Your drive shaft is slinging grease.I would say your rubber boot is blown.

Look closely at the cv boot for a rip.

Front you can remove until you find a replacement. Stock or aftermarket.

No noises yet? I would not keep driving it like that.
Assuming the jeeps lifted ... How much ?

Jeep has a 2.5 inch rough country and no noises out of the ordinary that I know of....


Could the lift have done it? It's only been on for about three weeks. Didn't think that was enough to need longer drive shafts or anything

Yes ... Do you have any type of caster correction, cam bolts/control arms ?

Well.... More caster will also increase pinion/DS angle. The reason I asked is because some people will run more positive caster not knowing the pinion angle is worse.

Drop brackets you have linked will force the pinion up when drooped protecting the DS.
At ride height you are shooting for stock caster which is 4*-5*
You provably are at 3*or so. Drop brackets will improve drivability too.

So repair the cv boot and throw some drop brackets on to avoid from happening again?

Sorry for the twenty questions I am decent with my mechanical knowledge on basic stuff... This is my first 4x4 so a front drive shaft in general throws me for a loop

You have to replace the whole shaft. Looks around in the classifieds/CL for a take off. I bought a spare for $75
Or Adams Ds offers a front for $325

How much lift did you actually get? Did you droop the axle too much off road ?
The front it tough, rear you can use CA's to better the angle. Front you are dealing with caster AND pinion. Stock Is around +2 pinion and +4 caster. You don't have arms so the pinion angle had been increased already lifted. Any more drivability will suffer.

Arms or drop brackets won't necessarily help. Like I said. The brackets do force the pinion up when dropped protecting the Ds. Overall nothing for angle.

Remove it. 4 front bolts and like 8 smaller TC bolts. Takes 15m and you can drive it without worry. Keep out of 4WD obviously.

You can't replace the boot. You need a new driveshaft.

They're out there cheap. Just make sure the shaft will fit. 2 door/4 door, manual/auto. I believe there is some differences.

Too bad thats such a bad tear. I had a grease slinging pinhole in my rear driveline boot and was able to re-pack it with grease and seal up the hole with blue RTV.

Got me through another 2 years of wheeling before the dealer noticed my "patch" and replaced the driveline under warranty.

I see stock JK drivelines for sale on CL here in the PNW fairly often.
Might be worth throwing a wanted ad up if your going to put another stock driveline in.

Talked to a driveline shop today.... He said on the older model he could take the drive shaft, cut it , and weld yokes onto it. Replacing he cv joint all together..... However he is un sure he is able to get parts he needs and it would still be almost $300

Thinking of just getting the Tom woods front drive shaft from quadratec

Just looked up Adams shafts... I like the fact that going with an upgraded one gets rid of this problem all together so I shouldn't have another future issue

Now is this something I can install my self without a lift? And should I jack up the jeep on stands or just leave it on the ground?

Leave it on the ground, put it in 4L and part/1st with the E-Brake set so it doesn't spin the T-Case flange on you when you are trying to line things up or fasten bolts. Depending you your suspension, you may be able to just slide right under there with all 4 wheels on the ground. If not get the front axle up on jack stands.
