If you have a NAPA with a machine shop near by, it's $15 per u-joint replacement and I think $30 for a carrier bearing.
and 35 per u-joint, and 50 per carrier bearing. i upgrade them when i have to change them.
neither of the napas around here have machine shops, they have phased that out over 2 decades ago out here.
plus napa is expensive for parts. i go to my local prop shop& driveline service shop, i hand it to them and they do it.
easy peazy, plus i boat with them. and they give me killer deals on parts.
i bought a 300 dollar crank driven water pump for 15 bucks, and he handed me a new impeller.
