Hi all. I am new to the forum actually this is my first forum. Not even sure anyone will get this . Lol but I wanted to share some information. I am the proud owner of a 2305. I have owned the tractor a little over 10 years now. Have had 0 problems . Until now . While servicing my transmission. I noticed my main drive shaft was loose at the rear u joint. Me being kind of a back yard mechanic I knew it was a bad u joint. I began making some phone calls in search of a u joint. I called my local JD dealer. The service dept said I couldnt buy just a u joint JD doesnt sell just a joint . I would have to purchase a new driveshaft at the low cost of $585.00. Oooh K. So I call another dealer about 30 minutes from my home. This guy said he could fix my problem in a couple days at a price between $800 and $1200.00. I said... for a u joint??!! The man replied . The whole top end of the tractor .. fenders , roll bar, seat, floor board dash etc will have to be removed to get to the u joint. Oooh K again. Thank you sir.. click. .. So I had already looked at the drive shaft and thought it looked alot like the same way all u joints in driveshafts are made. So I got under there and took the u joint out myself in about 30 minutes. I will go tomorrow and buy a new one and put it in. I just wanted to share this information with any other 2305 owners and also add that this u joint has a grease fitting. I do my own service to the tractor and my bad not greasing the joint. When I bought the tractor I read the owners manual for all grease points. This grease fitting is not in the manual . So heads up. If you didnt know that. You better get the grease gun under there. My tractor is at 700 hours and that was all the hours a fitting with no service could stand. I hope this information will help someone before it goes out or helps when it does either save someone heartache or a bill for $1200.00 for 1 hours work.
