T2 IRS Rear Stub Axle Bearing Replacement

 

Standard fitment on Bays and a common component of many IRS conversions on Split Screen Vans. The rear stub axle bearings can often be overlooked and only ever checked at the MOT stage. If yours have free play evident or wear when the wheel is spun by hand it might be time for some maintenance. Or when performing an IRS conversion a suitable time to replace the used bearings ahead of the upgrade.
