http://www.roadranger.com/rr/CustomerSupport/Support/Calculators/index.htm I used this when I decided to make my RT a RTO. I know it's a road ranger site but you enter you specs to determine road speed.

I've had luck with peppermint extract on cotton balls in old pie pans around various vehicles in the past

Ok watch your boost and if the boost drops out when you step on it and then lags up it could be the egr valve sticking open. I recently seen that happen on a 2009 and a 2011 GU. A lot of trouble shooting to determine that was happening. Other than checking with PTT you'd have to tear it apart to check to see if the valve sticks or hangs up.

Back off the slack adjuster and a heavy hammer. If that doesn't work I've used a porta-power off the frame. I only ran into that on a Freightliner with aluminum hubs.

Does throttle response cut out intermittently as this is happening?

Are they building any boost?

Is the notch for a wire to the horn button

Please post a picture. It might help explain things better. I've never seen a cutout on a steering wheel. I've seen some burns with cigarette lighters that the driver put in to let them know when wheels were straight. Other than that I've just seen cracks in the Bakelite.

Not to change the topic, but the special anniversary Granite pickup that is in or just out of production is an 800 hp 2800 ft/lbs MP8. From what I heard it's just a MP8 with a MP10 turbo (special manifold) and programming. This Granite is suppose to meet all the emissions standards. It has DPF and DEF. I think the different hp rating are just achieved by programming and maybe some small component changes.

^^^what he said

Not to be a smart ass but are you sure that wasn't the dye tracer for the refrigerant?

Here's a picture from the web. #9 is the bucket in question. The isolators(elephant pads) are #10 & #12. They have been part of the design from the start.

I've never seen it but I've heard of the buckets breaking on some older camelbacks. My dad had a F-model with 38k rears with aluminum bottoms. Pittsburgh Mack replaced them under recall. That was prob 40 years ago though. I agree with challenger; someone royally screwed up if that just had suspension work. I don't know if it did or didn't. It would make the most sense.

Seen these pictures on Facebook tonight. Looks like the rear elephant pad buckets broke and came off or bolts broke and came apart causing the rear axle to let loose. The driver walked away. There was a dash cam video but I didn't save the link. He was just driving a long and boom rollover.

Welcome fellow Pittsburgher although you're venturing close to Browns territory.

Don't get me wrong the new Macks aren't what they were 20 years ago let alone 14 years ago prior to Volvo. There is some product improvement in certain aspects on the newer trucks. There are pros and cons from before compared to now. Longevity has gone done but so has other brands, unfortunately, that's the market now. My point was don't blame the workers for the design flaws. In a sea of throwaways (ie Daimler, Navistar, Paccar,etc) Macks (gold bulldog spec) are better quality and easier to maintain. Freightliner materials are very cheaply produced. International are very badly designed for servicing. Peterbilt/KW have gone down in quality. The caveat with Mack is the issues with cups and injectors and some aftertreatment systems faults. From what I've heard, those issues are suppose to be resolved. Mack isn't what is used to be, but neither are the rest. I would hope with this new marketing campaign by Mack some customer attention comes back into play.

That's non-sense. The build quality has gone up in recent years and the personnel take pride in a good product. I've worked on all the major brands and Mack still makes quality trucks. Before it gets to the customer it's should get PDI at the dealership.

Look at the door tags for the Gvw rating if they are there. What's it's titled at?

Any external leaks around the surge tank or damp lines?

There is a datalink to the radio for whatever reason. Practically all new trucks have an inactive code for the radio. I just ignore them. But yes the radio is suppose to be "communicating" with the rest of the truck.

Holy crap! Get well soon!

Shift pattern is for a lo hole 6 speed. If it's a quad reverse would be in the main not aux like shown on tag.

One of the last of a dying breed. My condolences.Who did he pull for? What was the name of his trucking company? Was he a steehauler?

There are quite a bit of parts associated with that system from what I've seen. To myself, it doesn't seem surprising; suspension parts are expensive. If the cost of new is a factor, you could always look for a cutoff, but keep in mind the possibility of replacement of worn parts as well.

Your looking at a completely different suspension from the one you got. New holes have to be laid out and drilled in the frame. A full conversion for that price, if that includes the parts, isn't bad at all. If that's parts cost ($4700) that also sounds about right with all the new components needed for the new suspension.
