front wheel inner bearing measurement..

[gvy]

Hi,

Can someone measure the inner diameter measure of the front wheel inner bearing of a GT for me.

I recently replaced the right bearings and almost had an accident while driving at 130km/u and both inner and outer bearings were breaking.

I noticed afterwards that the inner wheel bearing, althoug the same as the one preveously installed, was not fitting the axe correct ?????

In my opinion, to fit the axe it should have an inner diameter of 27mm.
The ones I installed had an inner diameter of 29mm???

I see OGTS is selling new ones (nr 3038). I wonder if these have an inner diameter of 27mm to fit exactly the axe?
Please help me out, because this would meen I have been driving with the wrong bearings for some time....

on another forum, someone already stated that the inner diameter of the inner frontwheel bearing is 27mm.
Maybe someone here can confirm it?

I have a front suspension unit in pieces over at my workshop and will do a definative measurement next time I am over there (this week - with luck!)

Here are the sizes:

Inner (large) bearing - ID 1.0625" = 26.9875mm => so 27mm
OD 1.98" = 50.292mm
It is known as Wheel Bearing #A4 and is used on several Fords and many light trailers here.

Outer (small) bearing - ID 0.6875" = 17.4625mm => so 17.5mm
OD 1.57" = 39.878mm
It is known as Wheel Bearing #A1 and is used on the same vehicles here.

It looks very much like they are Inch Series bearings - not Metric sizes!

BTW - they should be a sliding fit on to the spindles as the inner race is designed to turn slowly to make sure that not just one area of the race bears the load - spreads the load right around the bearing. So, I always smear a little wheel bearing grease inside the bore before sliding them on to the spindle.
Sometimes the inner spins too much (usually due to over-filling the bearing with grease)which results in spindle wear - or too little (done up too tight or too tight on spindle or no pre-lube) which results in spalling on the downward facing part of the race.
