i just finished installed RCs high clearance skid plate, 1" motor lift, 1.25" body lift, sye, rear CV driveshaft... everything went in farely easy. my problem occurred once i started it after the installation of everything and took it on a test drive.
When i start the jeep there is a non steady knock coming from the tcase. when i accelerate to 35 mph it turns into a vicious vibration.. i have read that this signifies a loose chain but before i buy one.. i thought i'd ask around see what other people think.
i have a 05 TJ 4.0 6 speed trans. 32k miles with the 231 j tcase.
I suggest you download a parts breakdown of the transfer case to make sure everything is in the right place. I've just installed a SYE, driveshaft and control arms on my TJ with no issues. I did change the chain due to mine was stretched had a 155000 miles on it. I also rebuilt the transfer case with new bearings and seals.
no i didn't put adjustable arms.. the angle didn't seem bad at all. i wouldn't think i would have to change my chain due to the low miles on the jeep (32k). but i will crack it back open and look around. i'll let ya know what i find. if anything
that may be true but it doesn't explain the random knocking.. it's not a steady knock> . . . . . . . . . it's like .. . .... . . . . . .. . . . .. (just a guesstimate) i'm trying to upload a video of it
You are putting bad angles on your driveshaft which connects to the transfercase, the transfercase is now seeing forces at angles its not designed to see and its unhappy about it. Fix the angle first and see if your knock still exists.
