Happy New Year everyone. I can't seem to keep axle seals in the rear axle of my 2007.5 3500 Dually for more than 6 months to maybe a year before they start leaking. The wheel bearings look good and feel nice and smooth whenever I take this thing apart to change the seals so I doubt they're causing the issue but what do I know... I press them in square and even in my press when I install the new ones so they should be in there correctly... They're SKF seals if that makes any difference... Any ideas why this could be happening?

 

I did both sides on mine back in 11/2016 and they are still holding up fine. I used TIMKEN 710563 seals.

 

I did mine last year and they are still holding up I used this kit https://torqueking.com/product/8368/...it-with-tools/
