Driveshaft Issues with 2.5" Teraflex BB
Put a Teraflex BB on my 2012 2 door sport about 9000 miles ago (29,500 miles total). About 2 weeks ago while swapping in a rubi transfercase I noticed that the rubber boot was torn a bit on front ds (not a huge deal). Well today I look under and see that there is some grease spit out around CV joint by the transfercase. Didn't think I'd have trouble with DS with only 2.5", especially only 9000 miles later

I thought there were driveshaft issues with any lift on the 12+ 2drs? I know one issue was the exhaust loop being too close and melting the boot and so we either have to get a custom exhaust or eliminate the loop somehow.

Yup, mine did the same thing, but with the TF 2.5" coil lift. If I remember correctly, it was closer to 5,000 miles on the lift when it started slinging grease. I drove with it like that(and a torn off spline shaft boot) for over a year with no problems. When I switched over to a new shaft, I busted open the cv joint and was really surprised how much grease was still in there. I probably could have gone for quite a while longer on it.
