Well i think 🤔, i think i found my tcase leak. Tcase is still good just was leaking, well as i was looking to swap in the 231d and having a pita time trying to find the right rear extension housing, i noticed on the 231j that the front bearing retainer only had 1 bolt, which i didnt think nothing of before, until i was looking at the 231d and noticed 4 bolts holding that one together. So i pulled it and found it was to be sealed up and had no silicone with only the 1 bolt. So perhaps a little bit of goop and a few more bolts and I think it will be good to go back in. 😀 saves me some time-consuming work and will allow me to move on to more pressing issues. 😌 so will slap the tcase back in and move onto leaf springs.
