2003 400 sportsman.I have a clicking noise on the front in reverse when i'm on an incline or towing in reverse.Would it be bad u-joints.
If so does anybody have parts # for NAPA.If i'm going to replace one i might as well do the prop shaft and the other two up front.

Or should i be looking for another problem?

 

Sounds more like a CV joint going bad.

 

In addition to checking your cv's, take a look at front wheel bearings, balljoints, and the ujoints. Check out ebay if you need any of them. Pretty good deals on there.

 

Front drveline u-joints are a napa# 338,probably is a c-v joint, if so call the c-v man 1-800-338-2326 he also sells on e-bay, good products good service,

 

Thanks guys.I decided to change my hub fluids and take it all apart and noticed i have a crack in my roller cage in the hub,so i think i found where the clicking noise is coming from when in AWD in reverse.Should i look any further.

 

It wouldn't hurt to check it out while you have it apart.

 

havent heard of too many people having a roller cage cracked and clicking n the hub. check your bearings good while you have it apart as well. imo
