I understand I need to check it, but has anyone actually had that be the cause of hi/lo grind? I was thinking it may be easier just to pull whole tranny.

The tool number is straight out of the mack synchro repair manual. It hold everything in place when you take back cover off to do job with transmission still in truck. I did have the yoke off awhile ago to replace seal, you think that could be the issue???

I know this has been discussed and most likely the synchro clutches bad. I changed out the shift knob, valve that sits on top of transmission already. My main question is I cant find Kent-moore tool number J-41028 anywhere on internet. Anyone have one collecting dust?

All my linings and drums are good, I replaced 2 wheel seals and bearing sets over the summer and checked all bearings. I noticed some play in s cam but wanted to put it off until winter. I will be installing the 2 new slack adjusters next week. They are the standard 6" center to center 28 spline. I'm thinking that as long as I can maintain under 2" free stroke the cam play won't affect anything. Anybody that thinks you don't need to check brake adjustment daily with "automatic" slack adjusters should not have a CDL license. The manufacture state the adjusters should only be adjusted when first installed and when any brake work is done, that adjusting them any more than that actually wears them out prematurely. That does NOT mean you should not check the free play. Otherwise the only way you know adjuster has failed is when you can't stop or don't pass inspection.

drums and linings are good. There is play in cam through bushing, now this has me worried. I ordered 2 new slack adjusters.

no clicking

the adjuster ring thingy my finger is on has tons of slop in it, so not sure just cleaning would make these work again. I will adjust so 1 1/4" travel when applied, within 2 days have 3" of travel.

7/16 to adjust. Haldex. both on drivers side drive axles, they worked fine for 2 years and then didn't. Back in fall on time when I greased lot's of water came out.

2 of my slack adjusters are backing them self off and not making clicking noise when adjusting. Should I try to take apart and clean or just order new? and are ones on ebay worth anything or stay with OEM?

unfortunately the lightning bolt is never on long enough for me to get a code. I still can't translate abs codes I'm getting. ABS light is on most of the time.

No, I hold the 2 black buttons on dash, then I can cycle through the codes.

2005 Mack Granite CV713. ABS light comes on and off. Lightning bolt occasionally comes on. Pressing both black buttons on dash I'm getting codes S004-7 M136 and S002-08 M128. I know M128 is engine code and M136 ABS code, but it would be helpful to know specific code so I can tackle just one sensor. Thanks.

what O-ring? I put brand new one on down tube from dealer. I will take pictures Today.

I understand that. It's acting like it's randomly getting pressurized, like crankcase pressure. you can Idle for an hour after washing oil off and not see a drop, but then drive for awhile and be covered again. It's not a constant.

I've checked breather several times, I got the factory o'ring where down tube goes into oil fill tube. I just don't think it's meant to hold any kind of pressure there, just if oil splashed up.
