Re: Idler pully bearings

["jtrealtywebspannet" <jtrealty@xxxx>]

I don't think the idler pulley bearings are such a big deal. After 20+ 
years the lubricant has dryed out so they fail. Or the belt is too 
tight so they fail. The ordinary grade is more than sufficient but I 
guess it doesn't cost much to move up a grade if you want bulletproof. 
If you change the bearings every 10 years when you change the belt you 
would be very safe IMHO. How many people have anti-freeze in their "D" 
over 4 years!!!! Or hoses over 20+ years. Or brake fluid over 2 
years!!! Parts are not meant to last forever but people neglect things 
until they fail. Just because you don't put much mileage on your car 
doesn't mean you don't have to maintain it.
