New diff balls and rings...but still VERY notchy!

[Fiddybux]

I'm confused at this one.

Just rebuilt my X5 diff, and new ceramic diff balls and diff rings, and when tightened the diff is unbelievably notchy.

I haven't replaced the diff gear itself, but it looks okay, and I've rebuilt it several times using the same diff gear, and it's been okay before.

Any ideas? Is the diff gear that is warped / melted / worn?

Did you replace the thrust race?

[Fiddybux]

No actually I didn't, but I will now.

Sorted Lee....that was it!

Weird though, as I've changed so many diffs in the past few years, but never changed the thrust, and it's always been okay....up until now!

Still, thanks oh wise one!

No probs,

I find the thrust race causes the gritty feel. Sometimes fresh grease and a clean works other times it needs fresh balls.

Glad its sorted though

I remember now that when I dismantled it to chuck it all in white spirit for cleaning, that some of the thrust race bearings fell out of the plastic casing thing (LOSA3098)....should have noticed this as a warning sign!

So lesson learned there! Cheers Lee.
