Did the 9"/D44 ford axle swap on my MJ. Running the standard slip yoke rear d-shaft and a 231 t-case. When i'm on the gas there are no vibes, but as soon as I let off i get a nasty vibe sound that seems to be coming from the backend of the t-case. Angles look good. Actually the joint at the diff. looks to be right in line with the d-shaft. I know the two joints are supposed to split the difference as far as operating angles go, but, the joint at the slip yoke doesn't look too stressed either? I know, just go SYE. I'm saving up for the D300 swap so I don't wanna put any cash into the 231. thanks, judd oh yeah,
