Triumph Spitfire - Access to wheel bearings

I have a 1973 MBIV spit, I have a knocking sound coming from the rear and am 99% certain it's the wheel bearing. However even with the correct tool I can not remove the hub.

Any ideas?

On diagnosing rear end noises, see:

Stolen from John Kipping’s catalogue
(JK now incorporated into Canley Classics)

REAR END NOISES, Non-Rotaflex

Knock or rattle on slowing down? Yes >>>>>>>>>
No Not the diff. But the U/Js See Note 1

Continuous noise, Yes >>>>>>>>>
no change on acceleration Wheel bearings
or slowing down
Will be louder on one side See Note 2

No

Continuous noise, Yes >>>>>>>
Loudest on Differential acceleration See note 3

No


Get on the net!

Notes:
1/ Caused by:
A/ Worn U/J Replace
B/ Worn Yoke/flange
Circlip rubs and causes a shiny ring
Replace flange or halfshaft
C/ End float in U/J Oversized circlips [Only available from JK – JD]

2/ May be worse cornering. Usually means a new half shaft as well

3/ May disappear on deceleration. Neither one side or the other.
Usually a ‘whining’ noise .
Knocking, vibration or rattling are NOT caused by the diff.

On the basis of the above, and JK knows more about Triumphs than most, you have a U/J problem!

If you must have the hub off, the Churchill Hub puller SHOULD remove it. Once you have it as tight as you can (orig.tightened to 120ft/lbs remember) HIT the end bolt HARD with a HEAVY hammer. (Stand clear - it will fly off!)
