    Just got done with this chore about an hour ago. Discovered the OEM was shot yesterday. Had some time yesterday; so I asked the neighbor to come over and lend a hand so I could check ball joints and tie rod ends etc. Jack one side up with the floor jack, neighbor on the 4 ft. bar under the wheel drivers side lifting and releasing..................essentially no movement I could see or feel. Then on the same side, neighbor grabs wheel and 3 and 9 o'clock and tries turning wheel back and forth. No movement at tie rod end, but the the drag link end had 5/16" at least of movement, and the rubber boot was split. We did the same on the other side, and the results wer…

    Well I`m driving home this evening and realize that my vents are not changing status, and I can`t get into defrost mode. It seems like I have read before about 3rd gens having a notorious air diverter door? But I have no idea where it is located or how hard its going to be to get to. Has anyone had the opportunity to deal with this before??

    Hey guys. I've got to do wheel joints on the front axle. Now the driver side shaft just slides out. Now the passenger side shaft won't come out even prying against it. Is there a clip in the differential or what? Weird the driver side shaft just about falls out and slides in easy as pie. That passenger shaft is resisting the idea of coming out. Ideas, thoughts, or a bit of knowledge? Just finished up replacing both front unit bearings. This is when I found the passenger side shaft has a worn out wheel joint. I've got both wheel joints here and can easily do it at another time but the whole problem of the getting that passenger shaft out of the axle is my bigge…

    Towing this weekend I noticed that when my EGT's were about 1050° the needle would bounce from 1000-1100° at about a 2Hz rate, and then back to stable at 1050°. It did this 3 or 4 times on 2 grades (also did this once last winter at the 500-600° range). Otherwise it's smooth and operates as it did when new in 2007.I presume the stepper motor is failing? Could it be the thermocouple? Any opinions on if this will effect the reading when it's not bouncing?

    Alright folks I have a friend that has a 06 CR and his a/c isnt working. He says that there is power to the fuse but the compressor wont turn on, cycle or anything. I did try to bypass the low pressure switch to see if it was low on freon but still nothing happened.

    Hi guy's, greeting from snowy Michigan! This has been my first winter with the Jr. Cummins up here and I've been very impressed! No problems at all starting in temps as low as 18 below (Not plugged in) she's impressed the other diesel owners at work aswell , they pretty much don't drive theirs in the winter,and when they do, they all plug them in . Anyway back on topic- when I rolled into the cottage tonight and flipped off the lights , I noticed that when I had my foot on the brake , my right front turn signal was glowing dimly, let off brake light goes out. So I did a walk around and checked all the lights and everything but a front side marker was working. Rig…

    I'm having troubles with my truck, I can't get it started right now. So I'm trying to go through a do some trouble shooting. One code though the truck is throwing is a P0193, I got a rail pressure gauge in the mail today ,but it hooks up electronically too so that not a lot of help. I was just going to replace the sensor, but what has thrown me off is that I hooked up the electronic rail pressure sensor and it pegs out, which makes sense because the truck says its reading high too. But when I unplug the harness from the sensor then try and crank the truck the gauge still pegs out. I would think it should just read 0, since its not hooked up to the sensor. which this kinda…

    After install of the insight I set the guages to read boost and frp. the highest the boost got when getting on it was 27.8 and 1.9 crusing. the fuel rail pressure at idle reads 5.5kpsi and and will hit around 20 kpsi when on it and crusing sits about 7 to 9 kpsi. Do these numbers sound right??

    Is there any confirmed information on better mpg with a injector upgrade? I have read alot of posts that claim better mpg but it doesnt seem to make sense a larger injector would increase mpg. It is my thought for example a 50hp above stock injector would have a larger opening and work well at higher rpm but not as well as stock if you are driving for milage. The fuel droplets would have to be larger under low load conditions from the larger injector. That would be counter productive to complete combustion and not better for mpg. The site is coming along nice alot of good information there.

    Just thought I would share what took me 16 hours to find in case someone has the issue in the future. A customer traveling through on I-40 with a fifth wheel rv in tow got a check engine light and stopped by the shop for us to have a look. Truck has 212,000 miles. Hooked up Snap-on diagnostic. Found a stored P0341 fault. Cleared fault and started engine and watched live data on the Snap-on. Cam speed readings were all over the place. Swapped places with CKP and CMP sensors and still had erratic cam speed readings. Pulled entire engine sensor harness off of engine to give a thorough inspection. Found 2 wires on CMP sensor plug in bad shape so I replaced all 3 w…

    My truck is a 2004, since I have it the heater is not blowing a lot of heat during winter, this not realy a problem for me but my wife and my kids dont realy like the cold. I change the thermostat, I put a rubber mat to close 75% of the rad, the T is rising like normal but the fan is blowing cold air most of the time. Where I work I drive some newer cummins, 2006, 2007, and they blow heat like hell, the T just start to raise and the fan blow hot air. I dont now if some door in the blowing system are broken or what, last summer I check if the motor move the door when I move the control and everithing was looking fine, Yesterday it was -35 C here in Canada and the cab start…

    I've got a serious question here. All these diesel "fuel system cleaners" out there. You know, PS, Lucas, Howes, etc. What are they actually cleaning???? What needs to be "cleaned" on the INSIDE of our fuel systems???? Diesel is unlike gas in that is doesn't evaporate readily and leave varnish type deposits. Diesel is oil. When I did my fuel tank vent mod, I had to drop the fuel tank. It was pristine on the inside!!! When I added my GDP Walbro lift pump system, looked inside the lines I didn't need, and didn't see any deposits. Occasionally I find some "remnants" in the bottom of the fuel filter canister, but isn't that what my 2 fuel filters are for???? Do these "clea…
