I have a 1999 blazier 4 w/d I broke a gear in the axle so i replaced the axle the gear ratio is the same gu6 was the code on the glove box. after i swaped axles out I have a vibration , so i jacked blazer back up and noticed that the drive shaft wobbles at axel end I know that there is 2 different types pf axles for that year 1 buffalo axel and the other i cant remember so I am thinking that the drive shaft dose not match the axle so my question is can iswap axle yoke out and that woulds take care of it or will the match

 

Have you tried rotating the driveshaft 90 degrees and reinstalling it? Give that a shot first.

 

ok i will try that real quick

 

okwell that seemed to help still have a small vibration at 55mph but that could be the tiers thanks for the help
