my front differential is engaged full-time Will it hurt it to trail ride in high? How fast can I ride? I am going to repair it but don't have time before this weekend.

 

Since you don't say what model and year I'll just take a wild guess. If it's a Sportsman or Scrambler with the 4WD in the hubs check your hub fluid. Sometimes changing the fluid and making sure it's full helps with 4WD problems. If the 4WD is in the diff like it sounds like you may have a cracked roller cage. If you go riding with it that way it will make it worse.

 

 

can't say about Polaris but my Kawasaki Praire was full time 4wd and it ran extremely well for the 16 years I owned it. Rode trails, plowed snow and used it as a tractor on my property with never an issue!!

 

Polaris doesn't have a limited slip differential. When the 4x4 engages all 4 wheels are locked in.
