VIN: 7C532829
1. What is normal max boost on this truck? Say 1500rpm in tenth, I'm seeing about 28psi. Turbo was barking a lot at full throttle. I unplugged the EGR valve, and it quit doing that, but max boost stayed the same.
2. Gear shifter clicking side to side. I'm not talking about normal drivetrain flex. If I'm loaded and give it throttle, it will "click" to the side. Enough to move the top of the shifter about 2 inches. If I let off the throttle, it will click back to the other side.
3. Grinding noise when I push in the clutch. It grinds as through the entire range of motion, from release, all the way to the tranny brake.
4. When I accelerate loaded, and the truck flexes, I hear air releasing somewhere that releases based on flex if that makes any sense.
5. Sometimes when I start the truck, the starter solenoid will engage and disengage rapidly four or five times before it "catches" and starts the truck.
Thanks in advance for any help.

#2: Check the engine mounts. I'd check the cab mounts too. Never know, frame flex could be shifting the cab.
#3: Is it grinding only while the engine's running? If so, could be the pilot bearing or the release bearing.
#4: Random guess but maybe turbo actuator (if it has one)? Maybe a boost leak?
#5: Sounds like the solenoid on the starter could be on its way out.stillwurkin and God prefers Diesels Thank this. -

#2. What AModelCAT said. The front cab mounts are aluminum and are prone to cracking due to corrosion. Replacing the rubber front cab mounts actually fixed my clutch brake issues on my 9400.
Also make sure the trans is not separating from the engine because of loose/broken bolts.stillwurkin and God prefers Diesels Thank this. -
#3 - thrust bearing well greased?
#4 - leveling is common, but I’ve never been able to audibly hear while driving, only when I park on uneven surface.stillwurkin and God prefers Diesels Thank this. -

Bonus question: I've got 2.75" between top of U-bolts and axle stop on my front drive, but 3 5/8 on the rear axle. Does only the front axle matter when it comes to ride height?
