Wouldnt the only fix be to shorten the tail shaft to compensate for the difference?What sort of noises do you sedan boys get when you stuff your CVs?On a separate issue, my cars having a hard time spinning the wheels on a standstill, it will just sit at 2.5K rpm and doesn't budge. I have a feeling that might be caused by a sticky boost solenoid as I haven't done any maintenance to that yet.Any ideas guys?Jarrod.

You noise will typically be associated to the diff, but more hopefully... just a wheel bearing.

Jman there is two small spacers under the centre hanger support bearing. I have read a couple of Mal Woods posts describing vibration and noise cause be the incorrect spacers of lack of spacer. The "oil" may be excess grease that has been thrown from the bearing, Or it could be coming from the rear seal on the gear box.

I believe it was a quality issue with the bearings, first one was new under warranty at 7,500k and rthe second was a rebuild which is still going. Usually whines at about 80 to 110k at steady speed.Cheers Link to comment https://www.fordxr6turbo.com/forum/topic/48622-ute-rear-end-problem/#findComment-718184 Share on other sites More sharing options...

He can rebuild it and spec it all out better, but would prefer to use a KAAZ diff.Has anyone used one before?I've read another bloke on here got one and said it worked GREAT, but was very noisy.Whats a zippy dif gear to use with the ZF?
