Hey I have a 1997 Suzuki 250 quadrunner 4x4.  I use it mostly for working around the house and trail riding.  When I put it in 4x4 and turn the wheels right or left the right front wheel pops real bad?  What do yall think this might be? 

I dont work on it much but would like to start.

Thanks Dave

maybe a bad bearing somewhere  

4x4 and when you turn sounds like a constant velocity joint or universal going bad. especially if it's only in 4x4. how difficult that will be to replace is going to depend alot on which it is. universal joints can be relatively inexpensive while a CV joint is going to cost a bit more coin.
