Since my CTIS is not working, I manually aired up the tires to 80 psi. Tires show a maximum of 100 psi. CTIS trouble guide says tires should be at 61 psi on highway. Does anyone know if the 80 psi will cause any problems with the CTIS?

All in all, I am very happy with the truck. I will be adding more power later. 300 to 350 hp would be fine. Our 2012 Ford PSD has 400 hp and 800 ft. lbs. torque.

LOL,,, that would be plan D

You sound like a happy person,,, have a great day.

It was a near new 3/8 inch steal cable. It broke in half in the middle of the cable. The cable just snapped. Of course, no one was around and I was in the cab of the truck. No safety issues here. Where the stumps are, I am unable to push them, just pull on them. Like I said before, I will find a...

On to plan C Plan A was to use a chain and M923a2 and pull out tree stumps. :tank: Some on this forum said I would break the chain. So Plan B was to use steal cable and M923a2 and pull out tree stumps. :driver: Now I have two "halves" of a steal cable. On to plan C Plan C , find a stump...

Very good information,,, Thanks.

By disconnecting the control box, do you mean the electrical connection?

Thank you for the picture. Is that all you need to do to deactivate the CTIS?

Yes, but I will look again.

Ok,, I have looked and looked at past search threads on the CTIS, but have not found a step by step procedure on how to remove the CTIS. If anyone posted this, I can not find it. Any help would be appreciated.

I have been reading up on the CTIS, and found that when all lights blink, you have a problem. I did notice that before the lights started blinking, I heard a loud air release, like a pop off valve blew on a air compressor. I have not read about a fix for this yet, nor what might be releasing all...

Way up north close to Redding. Thanks for all the help. Kenm352a told me about the axle hub bolts coming loose and then the oil leaks onto the wheel. Sure enough, that is exactly what was wrong with ours, the bolts where loose. Thanks Ken. This site has the most friendly and helpful people.

Great information... Thanks very much. With all your inputs, I think it will be no problem now. Today I saw fluid, "rear axle oil" dripping on the inside of the right rear wheel, then running down the tire to the ground. Not much on the ground, but a small stream from the axle housing. I need...

I will read the 10 again. I did not see that information on the first four times I read the 10. After about 50 times maybe I will get most of the information. LOL... I found it, thanks: Wheel stud nuts on left side have left-hand threads. Those on right side have right-hand threads. Studs...

Thanks, I will check them out... Normal thread pattern is "counter clockwise to remove lug nut". Which side has the "clockwise" to remove lug nut?

Yes I have a concrete driveway, but at 70 plus age, strength is not there anymore. Thanks for all the good ideas. One thing I have always been good at is, after identifying a problem, coming up with a new way to solve that problem. But if you guys have already come up with a good solution, no...

Ok,,, but how in the world do you move a 500 lb. tire? When I change our F250 PSD tire, I use a shovel to raise the wheel up to the lugs. If I used the shovel on these huge tires, it would break my shovel. If a tire falls flat, how do you get it up? How do you align the wheel with the lugs, and...

Does the hwy light flash on startup on the ctis control? I will check this out tomorrow. You may have to turn on the driving lights to see it. Does the ctis do a pressure test when the tanks reach around 120psi? Again I will check tomorrow. Wheelspinner; Thanks,, I found out that my air...

Well,,, this morning they delivered our truck. Boy is it huge. Everything works great. The only issue I see is that the passenger side front tire is lower than the rest. I thought that when it started that the CTIS would air it up to look like the others. It did not. It is low but not flat. What...
