I have a 2000 chevy blazer 4x4 LT all wheel drive and 4 wheel drive. cv axle what does high rider option mean?

 

The high rider option is the ZR2 RPO option. The ZR2 is lifted (taller and wider) and has a longer CV axle, so they're not interchangeable with normal S-series trucks.

 

I put the new front right cv axle on and it doesn't sound right. it works but just doesn't sound right. so I was looking at some stuff and seen some stuff on high rider zr2 . my brother told them everything they needed to know when he went to get the part. they gave him one with the zr2 high rider option. but I just checked the glove box and didn't see the zr2 . so I think that's the problem. the zr2 cv axle they gave him is in the blazer but don't sound right. going to order a new one without the zr2 option.
