RowdyRebel Posted May 21, 2016 Share Posted May 21, 2016 Greased the Mack today, and when checking oil in the diffs, found this little gem stuck to the magnetic fill plug: Quote When approaching a 4-way stop, the vehicle with the biggest tires has the right of way!

HeavyGunner Posted May 21, 2016 Share Posted May 21, 2016 I'd be worried. Must be the rest of that gem getting ready to scatter and really bungle things up. 1 Quote The problems we face today exist because the people who work for a living are outnumbered by the people who vote for a living.The government can only "give" someone what they first take from another.

1958 F.W.D. Posted May 21, 2016 Share Posted May 21, 2016 Almost looks like a retaining ring or a snap ring of some kind. I don't know Mack rears at all but if it were my truck I'd be pulling the plate off and doing an inspection.

mrsmackpaul Posted May 22, 2016 Share Posted May 22, 2016 If I found that I would be looking for a spare day or two and lift the center out and at least see what you can find you look and not find anything wrong may look and find you found it just in time for a bearing or two Either way it wont cost much to have a look and you can at least make a judgement call from that Paul Quote Link to comment Share on other sites More sharing options...

Mike Posted May 26, 2016 Share Posted May 26, 2016 I would run right down to my local MACK DEALER and see if they have one of those whatcha ma callit's. They need your money. Quote Link to comment Share on other sites More sharing options...
Brian Blaylock Posted May 26, 2016 Share Posted May 26, 2016 My guess would be bearing cage also when looking for the source don't forget their is a remote possibility it could be part of a wheel bearing Quote Link to comment Share on other sites More sharing options...
