Good question, I put some 4.5 springs in mine and it didn't take long for mine to start grease slinging. I'm wondering how long it's gonna last.

 

All depends on how long it has been doing it and how you drive, but I would order a new one ASAP. Called Woods as soon as mine did that.

 

Well I've been through 3 stock drive shafts. Anywhere from 20-400 miles from my experience depending on your driving. I would pull it now and order a new one. Not woods tho. Unless you want it to look like mine after 6 months

Did you sand it befor you installed it ? Man my woods didn't look like that after 30k...

 

I agree^^^^ WTF? Mine doesnt look anything like that!!

 

Ok so what should I be out the look out for? What kinda noises, etc etc....

 

Just a few specs of grease is not a big deal, when it tears the boot you need to be concerned. You can also repack the grease in the CV joints of the stock shaft [I did a full write-up on that].

You will certainly get vibrations before a complete failure. Unfortunately with how many vibes and wiggles you get with a lifted JK at mud terrains, it's not always obvious.

My shaft squeaked out grease when I first put a budget boost on it....about 40,000 miles ago. Still on stock shafts with about 3.5" of lift on a 2dr.

 

Thats reassuring. Ill keep en eye on er and watch for any vibrations. With driveline vibrations, is it a strong, shake your whole Jeep kinda thing, or is it a more subtle, low tone vib felt in your feet as you drive? I have never experienced it before I want to know what to look out for....

 

So most here would agree that woods is the way to go?

 

There are many brands out there. Personally, when it comes time for me to get driveshafts, I will buy locally. If there are issues, which every driveshaft company tends to, you will have to pull it and drop $40? every time. If it's a vibration, broken, joint, whatever. Locally you can stop by and get it fixed on the spot, it can also be measured accurately to your rig versus a "it should be right" measurement.

However I think you are quite a ways away from needing a shaft. It's not quite one of those things I look forward to spending money on, so I maintain my stockers.

 

Had the same thing happen after my regear. The tech didn't install my pinion seal correctly and axle fluid ended up spraying in a circular pattern on my undercarriage. So my guess is: blown or badly installed pinion seal.

 

gear oil and the grease from the u joint are different
