Has anybody heard of these differentials progressively getting worse? I thought these were the ones that were good, good, good, then shot and can't drive anymore. I'm asking because under almost all left turns now my front left wheel like clunks and jumps at random like the differential is grinding gears or the cv shaft is grinding. It is just like a truck with the 4x4 engaged taking a hard turn on pavement. It tries to bind until it grinds/pops and then its good for a bit until it binds up again. I'm not sure if I should start out with taking out the axle or what I should do.

PS, like 5,000 miles ago I changed the fluid with Ford Honey (the expensive [censored]). I'll get a video uploaded tomorrow (yes it is so loud that you will be able to hear it )

That's exactly what happened with mine on my second diff. It popped on turns for a few months then progressively got worse until it popped going straight too.

It could be an axle tho. I hope for your sake it is.

Yea, thats how mine was...

Got an HMS trans out of the deal.
