Re: ZWG1140M 9145779820-00 bearing kit
PNC is 914579820 for a ZWG1140
We always put in tub rear which comes complete with bearings & seal part number for it is 4055150017,
normally the spider shaft is good & doesn’t need replaced unless you break the bolt taking it out.
The bearing seal the Chinese manufacturers used in these are crap which leads to water getting into the bearings.
You can get bearings & seal separately.
Seal 4055066726
Front bearing 4055087235
Rear bearing 4055087227
Spider if needed 4055066692
