Hi Graham

Once the unit is removed it takes about 5 mins if that to knock the old one out and put the new one in!

Easy job as long as you have circlip pliers, hammer and a drift.

If you are getting a slight whine and drumming noise it is most likely to be the quill shaft bearing.

Procedure is;

• Remove circlip from front of bearing
• hit the rear of the quill shaft (bit that mates with the diff) until the bearing is protruding about 3mm from the diff nose casing.
• Hit the front of the quill shaft to remove it.
• Drift bearing out from the rear.
• Using a block of wood replace new bearing
• Replace circlip
• Replace Quill Shaft
• Suggest you replace diff oil seal at same time.

One thing I discovered when I was doing mine was that the smaller washers from the main subframe mounts (WP828 and WP817) are the perfect size to use as a drift. No likelihood of leaving splinters in the bearing either then :P.
