GU wheel bearing locknut and washer install in GQ

[4x4falcon]

I've see lot's of references to this but nothing that actually shows what is done.

So here it is.

[4x4falcon]

Change GQ (possibly MQ/MK as well) double nut and lock washer to GU single locknut and washer.

The parts.


Top the GQ double nut and lockwasher, bottom the single GU locknut and washer.


Tools I used, not show is 8mm hex bit and ratchet.

Remove the freewheeling hub.



Nothing difficult here just undo the six bolts with an 8mm hex bit and ratchet. There is also no need to remove the wheel.

[4x4falcon]

Remove the hub locating ring (don't know if this is what it's really called but it stayed in the hub when I removed the freewheeling hub.

[4x4falcon]

Remove the circlip


Use external circlip pliers.

[4x4falcon]

Remove the inner part of the freewheeling hub.

[4x4falcon]

Straighten out the lockwasher tab for the outer locknut.


You can see the tab on the left of the nut. I used a pin punch and hammer to flatten it out.

[4x4falcon]

Remove the outer nut.


I had bought the 54mm hub socket so used that but it was not really necessary as the nut was only hand tight and a couple of taps with the pin punch and hammer would have loosened it.

Remove the lock washer.


I found this the most frustrating as it kept getting jammed on the thread and there's really not a lot of room to get hold of it. Using a magnetic pickup and long nose pliers for one side it came relatively easily but the other I had to get a small screwdriver to lever it out.

[4x4falcon]

Remove the inner nut.


Once again I used the socket but really not necessary.
