MK2 rear Cartridge Bearing upgrade UPDATED
« on: April 20, 2017, 11:02:25 pm »
Edit: This swap works in the same way the polo disk upgrade work except it's a bit easier to find parts because nobody wants drum brakes :) 
Drum brakes when fitted with new hardware are designed to last 200,000 miles. The polo 6n2 bearings are projected to last 100,000 to 140,000 miles. That means no more regreasing/adjusting the bearings ever again.

To give you an idea of what polo parts to buy here are some links

New Stub axle    VW part number : 6Q0501117

New bearing      VW part number : 6X0598477

New  200 mm Drum  VW part number : 6X0609617A
https://www.micksgarage.com/search-oenumber?oenumber=6X0609617A

New 180mm Drum  VW part number : 6X0609617
https://micksgarage.com/search-oenumber?oenumber=6X0609617


Just find a set of mk3 200mm drum assemblies, take off the mk3 drum, use the drum backing plate and mk3 brake shoe internals, attach the polo stuff and blam! You have a full set

UPDATE: The MK2 standard backing plate and drum internals should work. I test fitted the stub and the polo bearing but did not have the part numbers for the 180mm drum until recently. Based off the part dimensions the 180mm drum should fit but proceed at your own risk. The 180mm polo drum has not been tested yet





Update will follow as the parts come in

Things I know will bolt up:
Vw Polo 6n2/9n3 drum stub axles
Vw Polo 6n2 bearing/hub
Vw polo 200mm 6n2 drums

Things that also bolt up:
Vw mk3 200mm drum internals and backing plate

One thing you need to do is remove the abs ring on the bearing for everything to physically fit. I just used a flat head screwdriver to remove mine.


Edit: The drums are the same dimension as the Mk3 drums. This is going to work :)

Finished! The swap worked! You can use MK3 drum backing plate and brake hardware with the polo sealed bearing and drum!

No issues yet :) My rear tires are thanking me by not wearing into weird out of round shapes

I am very happy with  this setup. The rear bearing issue was going to be the make or break point on whether I kept the vw. No issues in the snow and no more fiddling with worn out bearings!

I wish I had seen this years ago for my  Mk2 Golf GTD. I hated that 1974 vintage bearing set up. Never seemed to get better than 30,000 miles, no matter what I did. ;D
