I have a 2012 B2320 with 950 hrs. It was one of a fleet of 12 that were owned by a Xmas tree farm & traded back in after 2 years use for new tractors. They were used for mowing/spraying with 3 point attachments. The dealership serviced the tractors, installed new LA304 loaders, & advertised them for sale for the unbelievable price of $10,500 (hard-earned Canadian $$$). Bought mine sight unseen trusting salesman's description & when delivered was in "like new" condition. When I questioned tread rubber seperating on front tires (rears like new) they gave me 2 brand new tires mounted on new rims for $100! Warranty ran out last summer & shortly after tach cable broke. Called to order new one & salesman sent one no charge. Tractor has been awesome for gardening, grading, bush hogging, snow removal & launching my boats. I have loaded tires (ww washer fluid) & a rear counterweight on the 3 point hitch that incorporates a 2 ft length of heavy gauge rr track, 2 cast iron weights & with a 2" hitch receiver (probably 200 - 250 lbs) - this is mounted most of the time & I use the tractor in 4wd most of the time. Recently noticed leakage of front diff. grease from top of right front spindle. When I pulled the dipstick/filler cap on the left side there was a noticeable pop of escaping air as if a vent might be plugged. I drilled a 1/16" hole in the cap , drained & replaced front diff. lube with 80w90. Seemed ok for a week or so but is now leaking again. From the parts diagrams looks like Kubota started with that seal & built a tractor around it! I have used the loader moving gravel/topsoil a bit last summer but hard to believe that would have stressed front axel enough to cause bearing/seal failure at the top of the spindle. When it bothers me bad enough to fix it (not a steady drip type leak, just seeping down side of spindle housing) should i replace upper bearing as well as seal? I have read where some guys found crud had collected around the seal & damaged it so it leaked, sound plausible?
