raybing Posted September 18 Share Posted September 18 Hello All, I have a 98 RD glider. The back rear axle is leaking gear lube from upper box into bottom. Not good. My busy tree moving season is just starting. So my question is about the seal and bearing repair.

0 mrsmackpaul Posted September 19 Share Posted September 19 Sounds like something may of let go Have you had the cover off the side and looked for any metal Drained the back end and looked for metal If theres no metal it might be just a seal As to how you fix it, I have never had a Mack diff center fail so I'm of no help here Paul Quote Link to comment https://www.bigmacktrucks.com/topic/75968-mack-camelback-44-rear-axle-repair/#findComment-583022 Share on other sites More sharing options...
0 mechohaulic Posted September 19 Share Posted September 19 when you state "leaking from top to bottom;" how did you determine.?? if you are checking top by removing 1 1/4 side cover plug finding it low then refilling ; then removing lower rear (square plug) finding it over full. the rear is over full. on a new rebuild the top is filled to plug. the oil will seek it's own level. oil from ring gear moves oil bottom to top. rear check plug is full system ok. external leak OR internal noise different subject. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75968-mack-camelback-44-rear-axle-repair/#findComment-583026 Share on other sites More sharing options...
0 mechohaulic Posted September 19 Share Posted September 19 it's a '98 glider ; any idea what yr the rears are or where they came out of ?? also being '98 to be more specific :: the top side cover plug may also be a square (3/4 ?) plug the 1 1/4 style goes back a few > shouldn't be an internal seal . leak external from top carrier through housing used to be large skinny o-ring, think that was done away with having invention of silicone goop.

0 raybing Posted September 20 Author Share Posted September 20 My ignorance is showing. The top box only carries a pint or so. As intended if filled to level it runs down to bottom. Thanks for answers 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75968-mack-camelback-44-rear-axle-repair/#findComment-583068 Share on other sites More sharing options...
