I got to thinking how often should you change the boot grease in the CV boots and the guy checking me in seem to knot really give me a good answer on when or how often the grease should be changed.

So I thought I am here just change the grease in all back 4 rather than just the inner left. Am I stupid or what. Should I call them back and just do the grease replacement and boot change on the inner left rear. I thought if that one was leaking it didn't make any sense to not just relplace the boot and clamp at regreasing the left inner boot.

My quad has 500 hours now it a utility one with an after market hour meter. I was having them change the differential and left rear inner boot gave them the parts minus the differential fluid and the and the bill was going to be $240 it would cost another $240 if I did all 4 which didn't sound right he said $80 a boot.

I somehow lost the upper paragraph. I had noticed thier was a light grease and dirt build up on a left rear inner boot. I had replaced this boot years ago because it was torn. Yamaha had changed the part so it was smaller. Anyway it obviously was slightly leaking. I bought a replacement boot, grease, and clamp as it didn't make any sense to replace the grease only, nor just the clamp as the cv boot was not torn, might as well relplace it while doing it.

That I know of there is no maintenance schedule for replacing the grease or greasing the CV joints inside of the boots.

Unless they are torn or leaking grease I would leave them alone.

This is one case where, “if it ain’t broke, don’t fix it” is real. The longer you can go without touching them, the less likely you will have problems.

Grease inside a cv boot is technically speaking, a lifetime product. Meaning no maintenance for the life of that part. As long as it remains clamped and sealed, no holes or rips, the grease should still be fine.
I've had a fwd car with a bit over 320000km on it and still had original front axels, CV joints were still fine when it was junked due to rusted frame.
To me, that right there is proof that it's fine provided no external contamination gets in.

Thanks you guys saved me $240. Unfortunately the service guy was very vague, he spoke like he had no clue, causing me to think I likely should do it my quad being 6 years old. I already change my oil with synthetic Yamaha oil and coolant every two years I put in 45 and 90 degree zirks which make that process supper easy. I am hesitant on changing my differential because of comments stripping threads but I am going to give it a shot. Next time I have to deal with a boot I am going to try it myself.
