LocoCampbell Posted August 17, 2018 Share Posted August 17, 2018 (edited) Thanks for the add! I’ve joined seeking help for my poorly Wrangler YJ. If anyone knows of an awesome mechanic in the Cambridge or East Anglia area, I’d appreciate the referral.

V Posted August 17, 2018 Share Posted August 17, 2018 It's worth the drive to TCJ in Northampton. 1 Quote Link to comment Share on other sites More sharing options...
LocoCampbell Posted August 21, 2018 Author Share Posted August 21, 2018 Thanks both, I appreciate the advice. TCJ, I’ve been chasing a bad grinding sound for a while. Looked at the rear differential, seems ok so thinking it may be the tranny. Sound gets worse the longer she’s driven in a day. If I’m turning at low speed in 4x4 high, it feels and sounds like she’s gonna rip herself apart. I’ve alread removed the limited slip plates to no avail. It a worrying problem for sure. Sounds like I’ll be making a trip to NH. Cheers for the advice guys. Quote Link to comment Share on other sites More sharing options...
V Posted August 22, 2018 Share Posted August 22, 2018 Do you have a vacuum disconnect front axle? I am not certain about the early 231 transfer cases but I remember they don't have a proper transfercase neutral. I wonder if the noise is the transfer case chain?

LocoCampbell Posted August 22, 2018 Author Share Posted August 22, 2018 I don’t know the answer to that but I’ll look into it and let you know. Cheers V. Quote Link to comment Share on other sites More sharing options...
V Posted August 22, 2018 Share Posted August 22, 2018 I am fairly certain on the early 231s that the front and rear shafts always rotate together which I'm guessing means the chain is rotating all the time too. If it is the chain, the cheapest fix is probably a used 231J from a 2.5 petrol or diesel XJ or from a KJ. It will enable you to convert the front axle to non-disconnect. The thing to watch out for will be spline count. I believe most UK RHD Jeeps with 231 transfer cases were 23 spline, but I have a sneaky suspicion that the early 231 YJs were 21 spline. I think you can swap input gears from one case to the other to get the right spline count if it is wrong. I have never done it myself. All my transfer case swaps have been the same spline count. 1 Quote Link to comment Share on other sites More sharing options...
