    Has anybody here seen this transfer case brace/bracket. I believe it was introduced at EJS this year.

    I have Tom Woods drive shafts (1310 front and 1350 rear) on my Unlimited and had been struggling with driveline vibration since fitting them. I've recently had both shafts balance and unis inspected. There was a uni on each shaft needed replacing and the rear shaft was found to be badly out of balance. This recent work went a long way to reducing the vibration, however i can still feel it ever so slightly, which i now put down to pinion angle. Very disappointed to be balancing and replacing unis on brand new shafts (less than 6 months old).
    Bundy's specs:
    - 2013 JKUR
    - AEV bullbar
    - AEV snorkel
    - Warn M8000
    - Gobi Stealth roofrack
    - Synergy coils & Fox remote reservoir shocks
    - Pro Comp Xtreme rims & BFG Mud-terrain tyres (285/70R17)

    Yeah, I'd be pissed! Mine's about as old and I'd like to think it's not out of balance, but that could be it. Once I adjust my caster by a degree as suggested, if I still have any vibration, it's going straight to the driveline shop for balancing.

    I am going thru the same thing with my tom woods shaft. 1350 front. I went and got it balanced and it still vibrates. It didn't help. He said he sees it often because the drive shafts are so large. The rotating mass gives vibration or something.


    Also a side note. I thought that if you get a tom woods driveshaft with there gold seal joints that they would give you a lifetime warranty. This is not true according to the man at the front desk. I was just told its a 6 month warranty.
    Maybe 6 months for gold seal is considered life time. I dunno.

    Yeah, saw it and, while it should help prevent a t-case from breaking apart, so will a set of drive shafts that are well balanced and not vibrating. For me, I prefer addressing the problem at the source but, that's just me.

    Honestly, I don't know why so many people think so highly of Tom Woods drive shafts especially when there are so many documented instances of poor balancing right out of the box and cheap Chinese u-joints that fail time and time again. Sorry to hear you guys having the problems that you have.

    Which driveshafts have you used on your builds? Ive never bought an aftermarket driveshaft and thought I would be getting a tom woods if I needed one down the road.

    I personally prefer JE Reel if only because they use made in the USA Neapco u-joints standard and I've never had an issue with the half a dozen shafts that I have gotten from them in the past for my various Jeeps and Jeep builds. I have also had good results with Coast and they use Spicer joints. I have also had custom shafts made by a then local socal shop and found them to be very good as well.

    Ok thanks I'll have to look into those. Now that I think about it I have heard of JE Reel before too.

    If I had my time over again, and knowing what I know now, then I wouldn't have fitted Tom Woods shafts. I was told by my local driveline specialist that the two Tom Woods unis which were replaced looked to have a poor quality seal setup, and he actually removed weights which weren't required, and shouldn't have be on there.

About us
“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
