I have a 2002 Honda TRX450FE Foreman ES. The rear axle was stripped inside the ring gear. The last owner has been welding the axle to the ring gear. The weld finally broke again and I am not going to keep welding it as he did. I need to replace the ring gear and the axle. My question is, can I replace just the ring gear and not the pinion or would I run into problems using a new ring gear on an old pinion?
