Rear axle is soaked, need help...

[JMBT]

Waterloo if the shops fix doesn’t hold and you have to do it again, it isn’t to bad of a job. I have Meritor rears and I have replaced both front and rear unit input shaft seals. The front is a little crazy because Meritor uses, at least on my MT40’s, an adjuster ring. You have to use a dial caliper to get the right in play and not get the ring too tight. There is also a special sealant required for the adjuster ring that allows you 15 minutes or so to futz with getting the iN play right. I have a tiger tool yoke puller and a 1” HF impact that worked great for the job. The front unit nut is listed at 900lbs, and the rear unit was 1100 so I used a torque amplifier and long torque wrench. Both nuts are supposed to have a bead of red lock tight. Hopefully you won’t have to mess with it again for a long while but if you do maybe this will help.
