Bearings and shafts

30th April 2010, 00:31

Hi, i have mk2 struts on my mk1. on both sides i have fitted the later model bearings (ones with the larger internal diameter), but on the N/S i am running a mk1 driveshaft that does not have the tapered end that the mk2 shaft has. the mk1 shaft is now dying as all the grease has escaped the cv joint and its beyond regreasing. im wondering if i should get another mk1 shaft, as no taper = no risk of damaging the bearing, or whether i should get a mk2 one. what would be the consequences of using a mk1 shaft with a mk2 bearing?

i understand that a mk2 shaft with a mk1 bearing would equal rapid bearing destruction due to the taper, but is it ok the other way round? thanks for reading lol

Fit the shaft to match the bearing mate, if you have the post 99 bearings youll want the tapered shafts both sides. No point in risking it with a pre 99 shaft if your replacing the shot one with a new unit anyway

that makes sense, thanks for your help. one last thing is it possible to tell which bearing is which by its appearance, or is it only determined by the interior diameter?

I couldnt honestly say mate, Ive never paid that much attention to them in that respect. As you say the best bet would be to measure it up, but if both were fitted at the same time theyll surely be the same

sorry to bump up an old thread, this might sound silly, but is it possible to fit a bearing back to front in the hub; is there a 'back' and 'front to the bearing?
