Did you try it with a load on ? Some components must be worn enough to be putting stress on those bolts. Also does the truck have the thick washer between bracket and banjo housing?
-
also What kind of suspension rating do you have ? Bronze bushings or rubber ones?
-
Drive the truck around in a circle without the torsion arm.if the wheels walk off while turning then ur trunnion or bushing might be extremely worn.therefore while turning loaded that single bracket is taking all the stress of keeping the bogie straight which causes the bolts to break.

I thought as much.i reckon all the chemical components in coolant along with the 12v power coming from those pins acted like an electrolysis machine and just ate them up.
-
Does this also happen to the engine oil sensor .when I pull the top connector from the ecm there was oil there also.
-
Only thing I see that's bothering me is that my oil and coolant temp gauges are staying around 160 degrees .they are usually around 185 for coolant and 200 for oil.wonder if the new ecm had gauges with different resistance values ??
-
I unplugged the coolant sensor plug and sure enough it was full of coolant
-
Wow.! I understand stand now.will look into it.thank you every one. Also will probably need to change the lower connector on the ecm...they are kinda corroded and were given me some pita this morning.i cleaned them out with some small picks but not real sure bout them.is it better to change cut and splice a new connector or install another harness?
-
bought a used ecm ,Truck running good .have a lighting bolt code for engine brake , reckon the truck the ecm came from had engine brake.
-
Part number seems to be a 12ms530m .there is one for sale used .local mack wants a fortune and not in stock.like always.does the new used one need to be reprogramed?
-
It wasnt the coolant sensor dripping.it was the over pressure line thats connected to the pressure cap that was routed and pointing down towards the connectors

Found the issue ..3 ecm pins have completely eroded off ..need a new ecm
-
After cleaning.im getting a " no info" on the dash.could the ecm be fried?
-
Found the bottom ecm connector full of coolant and grime.hopefully that solves it

I'm reviving this old tread because I'm having this same issue with the CV.Code 6-4. Last night I was on a job and truck started acting up. At first it seemed like the fitting on top of the oil filter housing had rubbed the insulation on the harness for the ecm.the fitting was kinda eaten up on one corner like if it had been shorting against something. I wrapped up everything in electrical tape yet issue still persist albeit less often than before.also top ecm connector had some oil . would this cause it to loose connection? What's the best way to clean up these connectors and pins? Thanks Red

I used a caliper micrometer to measure the ring and it was about 15mm .I built up the material in the fork and then ground it down to around 14.8 mm to give it some breathing room. The fork originally had a thickness of around 10.5 mm , those extra 4.5 was the needed push to make the low range clutch engage.
-
Update..I stick welded the worn part of the shift fork and built it back up... transmission is running like a champ now...I'mma start looking for a suitable replacement , preferably a 8ll . Thanks to all of yall . Red
-
I have owned the truck since late last year and it always had that symptom.the transmission seems to have been rebuilt not long ago by weller.it has a Weller tag.i will call them and see if it may have warranty or at least a quote on repairs.
-
I will do that.by chance does anyone have pai part numbers for these two items ?local mack wants 488$ for shift fork alone.thanks

Finally got back from a much needed vacation and got to work on the transmission.took the rear cover off and below are the pictures of what seems to be the culprit. Not sure what the specifications are for shift fork wear but this one seems to be very worn.please advice. Thanks Red

05 Granite CV713 steer wheels and tires
R.E.D replied to Deere Mack's topic in Driveline and Suspension
I personally prefer a wider tire because it allows me to "float" easier in rough terrain due to the increased surface area.also at least in my area it's also a dot deterrent.they see a quad axle truck with thinner tires and automatically assume your overweight in your steer axle , even though 315 are usually rated at 10k lbs just like 385 or 425.and once your pulled over and noticed your not overweight they find an excuse to issue warnings and fines.but like I said , this is in my area.
