I've replaced a front wheel bearing twice with 2 different makes of bearings and still have excessive play. The inner cones are very tight on the hub and the outer cups are very tight in the upright.

Are shims available to add behind the out cups to push the outer cups further apart to tighten the bearing, machining a thou off an inner cone’s front face would have the same effect.

Shame they don’t have an adjustment nut with a split pin like the good old days.
Cheers

Last week I torqued my new ones up to 240 in the vice....rammed full with lovely new greese they are just nice and firm to turn....should be perfect when warmed up in use.

Have you got the right bearing kits would be my first check....hub check 2nd....flange check third.....torque setting 4th.

Don't quite follow your 2nd para....you'd have to shim out the outer races inside the hub to push them further apart to take up bearing slack....bit of a guessing game as to how many though and obtaining shim in suitable size and a range of thicknesses sounds like not much fun !

The pre-load is built into the bearing kit/set races so unless the hub nut is damaged/scored on the clamping face and your saying the outer and inner cups are secure then this is the only way you can have play/float scratchchin unless the bearings are of ste quality frown a lot of questionable quality stuff around at the moment especially bearings frown I would only use shims for a last resort wink

Steve, I am not an expert but it sounds a bit questionable to me, something sounds wrong. I didn't thnk there was any adjustment nor any shimming. Assuming a 4.3 has the same bearings as a 500, I've got my hubs stripped down so can do some measurements next Friday on my return to Blighty, if that helps.

Let me know, Pete

Correct, no adjustment and no shims the factory pre-load is build into the bearing kit with the nut torqued correctly wink

Regardless of the pre-load, did you manage to do them with the upright in situ or was it an 'on the bench' job?

I know ... I know... I'm just so cheesed off I was only living in hope.

Chuggaboom or anyone else that has successfully fitted a new bearing kit can you please give me the make and bearing kit part number, thanks.

Pete, Yes please, that's the best offer I've had all year and their is no pressure. Some very accurate measurements may help me identify if I need a new hub or upright. Would you mind measuring the length of a bearing and inside the upright the gap between where the outer cups sit.

Thanks everyone for confirming my thoughts, I just needed to hear it from some else before I start buying hubs and uprights.

Thanks & Cheers Gents

Pete,
Thanks for your help over the phone, I'll let you know how I get on. I'm not in a rush at the moment to take my Griff a part again while I'm enjoying the overdue dry weather.
Cheers, Steve.
P.S. I hope to see you at the TVR Berkshire meeting next week on Tuesday.
