Anybody tried clocking a 208?

    I've been going back and forth on the t-case issue for some time now, and think I'll probably stick with the 208 for financial reasons. I plan on converting it to a fixed yoke, partially so I can raise it back up to the stock position. Was wondering if anyone has tried clocking the t-case a bit to raise the front output. I haven't crawled under the truck yet to check the floor clearance, but a bit of sledgehammering doesn't bother me (it's the passenger side footwell anyway, right?).

    I wanted to do the same thing on my NP 241 t-case but whe I got the body off last week & sized it up, the bolt paattern is not symmetrical so you can't just unbolt it, rotate it bolt hole & then bolt it back on. Besides, there doesn't appear to be alot of room between the front driveshaft & the tranny pan in mine (I've got a 700-R4).

    Now there is a company that makes a product for indexing the Dana 300 in a jeep & they told me they thought it could work for the NP 241.

    Here's the review: <A target="_blank" HREF=http://www.bc4x4.com/pv/yj/go2twister/go2twister.cfm>http://www.bc4x4.com/pv/yj/go2twister/go2twister.cfm</A>

    I've never thought about it. While it does sound good in theory, the first thing that comes to mind is the drain and fill holes. How will you get the correct amount in there if fill plug is not up as high as it should be? But this is just a thought without looking at it.

    Also, on another thought. If you do this, it will move the front drive shaft off line with the front diff. So I dont think this would be possible. If you get the slip yoke eliminator and raise the T-case back upto the frame, you will have enough clearance for the front driveshaft.

    I kind of assumed I'd have to drill a new bolt pattern. I don't think the driveshaft alignment would be a problem, lot of 4x4s aren't lined up real well from the factory. The 700R4 clelarance might be an issue though, I know they stick out farther on the passenger side, and driveshaft clearance is real tight when using a Dana 300 with one. I think by raising a t-case back up to the factory position (it's dropped now), my CV angle will improve, besides I only run about 3" of lift.

    Yeah, my front driveshaft is hitting the exhaust collector pipe. Well, it rubs it. I can see a clean rings all the way around the driveshaft, and my front output shaft seal on the 241 is now leaking. Im assuming its from the CV being maxxed out and putting more strain on the front of the T-case. But it could just be that time.

    I just went out and looked at it, it would take some floor bashing. Next time I have my grubbies on I'll get a better look, to see where the baching would have to be. The trans clearance looks OK. I run full length headers that Y behind the t-case, didn't look to close at the exhuast clearance.

    Let us know how you make out, Pete. My problem won't be floor clearance with my new frame; I'll just build in the clearance. I am interested though in how the clocking works out with the trans adapter.

    Good Luck

    It'll be a while until I can really do much to the truck, I've got to focus on finishing my projects for the end of the semester (mid May).
