LN IMS retrofit

[Col986]

I'm in the process of installing the LN single row IMSB retrofit in a 2004 S.
Living in Perth Australia, the closest approved shop is in Sydney or Melbourne, the equivalent of LA to NYC. So I basically have no option but to do it myself or at a shop with no approval.

Having read almost every comment written on all the forums, I can see thorough preparation & research is a necessity, so I've opted for the DIY.

It's a shame LN provide no support, yet charge a premium for their ceramic bearing. My first choice would be to instal the double row bearing, however the faultless tool cost rules this out.

So far my factory single row bearing has lasted 11 years or 80,000km, yet the LN bearing I bought has a 4 year or 40,000 miles service life, though I'm sure it will go longer.

My question is, as I only do 3000 miles a year, why is there the 4 year service life? Do I really need to change it again in 4 years or 12,000 miles!

The only time life item on the LN bearing I can see is the outer seal? I also change my oil each year with Joe Gibbs DT40 (3000 miles or 5000km).

My thanks to all the contributors, once you sift through all the threads on this and other forums, the information gained for DIYers is invaluable.
