Steelman Wireless ChassisEAR

[dbertheau]

I recently purchased a Steelman Wireless ChassisEAR 97202 to help identify where a noise in my drive train was coming from (2006 dodge ram 2500 cummins 5.9L 4X4 quad cab long bed 48RE auto.)  The tool was around $200 on Amazon.

 

I had a groan/grind noise that occurred when power applied and just before shift from 2nd to 3rd, from 3rd to 4th and in 4th when torque converter locked.  Myself and my mechanic agreed that it was rear pinion bearings...around 185,000 miles on bearings.  Changed rear pinion bearings and sound was still there.  I recently had a 5" aluminum single piece rear drive shaft put on...the mechanic said that the noise was probably the large drive shaft acting as a megaphone and may not be an issue?????

 

I ordered the ChassisEAR to help diagnose the noise.  When I received the tool I connected sensors to a number of areas...rear differential, output shaft area of the transfer case, middle of the transfer case and output shaft area on the transmission.

 

For the most part all sensors were quiet except the middle of the transfer case sensor.  Could clearly hear a stretched chain slapping around and especially when the high speed load situation occurred.

 

Wish I would have used the ChassisEAR first, before replacing the pinion bearings...actually, I'm fine with preventative maintenance and bearings had 185,000 miles, so no big deal.

 

I'm extremely happy with this new tool and would highly recommend it....

Thanks Dave. I think this would have paid for itself not having to do the pinion bearing lol. O well, I'm like you, its going to need replaced sometime, better it be when I want to do it instead of when the truck decides its ready ha-ha.
