a lot of people now run coast because they cost the same, if not less than the more popular brands out there AND, come with quality spicer u-joints standard - no upgrades necessary. having said that, so long as it's well balanced and come with good u-joints, a drive shaft is pretty much a drive shaft.

drumnatural...what size lift do you have?

wayoflife

in his first post, he said "2.5 OME lift with teraflex LCAs"

OME gives u more then just the advertised 2" lift. It's as much as 3" plus if u get the heavy load springs.

2.5" is my rough estimate

I have been running my stock front driveshaft for almost 2 years with that same line of grease that spitted out. In my opinion, it is caused by the excessive angle resulting in the rubber of the CV boot getting pushed in a little squeezing some of the grease out. Kinda like taking the cap off of a brand new tube of toothpaste...it's good as long as you don't try to bend the tube or it will start pushing the toothpaste out. Sorry for the funny analogy, but thats kinda how I would describe it. There's nothing wrong with the boot, nothing wrong with the bearings so long as it hasn't pushed all the grease out and there is no noise. What I do is just every now and then I check to make sure there is no new grease spatters that came out. I also run my fingers over the boot and give a little squeeze...you can feel whether or not there is still grease in the boot. I honestly do not see why you would need to right away run to the 4x4 shop for a new driveshaft....just keep an eye on the stock one for now and save up some money knowing that eventually you will have to replace it. But that's just my opinion and I am pretty much a noob, so take it for what it's worth.

That's what I plan on doing. Watching and listening. I'm doing my homework now so I know exactly what I want/need when the time comes.

I have the same exact thing happening under my JK. I have not taken my Jeep off road to 'twist' it up yet. I will be keeping an eye on the front DS and will be saving for a snew/better one if it goes out.

With the the Poison Spyder Bumper/Winch up front and a future PS or AEV bumper in the rear, combined with gear and a passenger, I plan on going HD. I'm sick of losing all my lift once its weighed down, but perhaps that is just a result of the stock suspension/spacer combo? I just want it done right, too many people reporting issues after not having done the homework. I'm thankful for these posts!

If you go off-road and flex the DS bends even more with the articulation of the front end. It'll spit a line of grease, quit, then if you wheel, spit more grease, quit, etc. Until most if not all the grease is gone. Therefore as WOL had mentioned before, kinda sucks when it gives its last breathe when your on a trail. Mine lasted about a year on a 4in lift only wheeling it about 4 times during that period.

Lost the grease out of my front driveshaft @ 15k. Fortunately my Dealer replaced it NC under the lifetime warranty. At that time I did already have my lift installed but as long as you are less that 4" they will take care of it. I knew then new shafts were coming but heck it bought me some time.
