terry Posted December 14, 2020 Share Posted December 14, 2020 What did you use to drive the seal in with? terry Quote Link to comment https://www.bigmacktrucks.com/topic/65234-2000-mack-rd-688-rear-wheel-seal/#findComment-465460 Share on other sites More sharing options...
Joey Mack Posted December 14, 2020 Share Posted December 14, 2020 I forgot to ask if you have mack rears,, also, was there a wear ring on the spindle and you installed 393-0173 stemco, that is why it was tight... the wear ring needs to come off, buff the spindle and if it is not damaged you can use the stemco seal, if it ha light damage, the 2 piece stemco seal kit is what you need... there are specific drivers to do the installs, can you post the stemco seal you used, I have a chart and can cross it that way....
