06' Apex GT
I'm replacing my drive shaft on my 06' GT at just shy of 6k as preventative maintenance, as long as I have it apart I'm going to do the jackshaft bearing as well. I inspect or replace every other bearing on the sled annually, but I have never paid any attention to the bearings inside the chaincase. I assume these are a non-issue due to the oil bath, but has anyone ever had an issue with them? I'm thinking about replacing them as long as i'm in there, but maybe it's not worth spending the extra hundo if they never have issues?

What about the oil seals, should I replace those?

Like many on this site I do a ton of PM so I don't miss a day or two and ruin a trip, just no need to spend the extra money if I don't have to...

Thanks!
 
I would replace chain case bearings also, The wear from the chain and gears gets in the lube and settles in the bearings, you know that black grit you find in the case when you service it. (JMO)
