Noise In The Rear

I brought my 05' 1500 crew cab new, late in the year, and have been complaining about the rear brakes / noise in the rear since.

 

I now have 30k on the truck and have been going to the dealership every 3k or sooner for oil changes / maintenance. I have mentioned that there is something with the rear brakes since new (75 miles) but they never seem to find any noise or grinding that I hear.

 

The last visit I again complained and they told me that after 4 road tests by 2 different technicians, they think the noise was found. First it was the u-joints, then they said it was the drive shaft (10382033) which is a special order part. They found this through a TSB they said. I was ensured, again, by the dealership that there are no issues with the brakes (but @ 3k they resurfaced the front brakes when I complained of the noise).

 

I keep detailed records of the truck (milage, service, etc) and need some information. Does this diagonses make sence? So far I have not paid for anything by normal maintenance and now beginning to feel that the end of that is near.

 

The squeeking noise comes from the rear drivers side; it happens on slow decelleration. There is also a pulsatating feel from the back sometimes that comes and goes with rotation of the wheel.

 

There are numerous TSB about my truck, but I need to be more educated. Alldata.com only gives brief one line info about it.

 

Can anyone provide assistance?

I used to have exactly what you described. Does it sound like a spring or a pop? A way you can test this is get going about 30mph and then put the parking brake down about 1 or 2 clicks (enough for it to engage). Oh, yeah you have drums in the rear right?

 

If so, when you apply the parking brake and you hear noises and the rear end starts to 'jump' or pulsate then your drums are out of round. I made a post a while back with all the part numbers to completely redo the brakes with front discs and rear drums. The front numbers I used are stock pads and powerslot rotors and the rear is all GM drums, shoes, and springs. Click my profile or search and you will find it.

 

What was happening is when you start slowing since the drum is out of round it will hit your emergency brake shoe and actually pull on it then releasing. When your drums get warmed up they expand and the noise and pulsation start to dissipate. Does this happen after the truck has been sitting awhile?

 

Try this with your truck and if any of the symptoms happen that I described then you need new drums. Its your choice to get new shoes but I did becuz my emergency shoe ended up being damaged from the drum hitting it. It costs about 400 bucks for parts and I had the dealer install it which was about 200 bucks. I wanted to do the drums myself but didnt have time to mess with it and had the dealer do it. The choice it urs.

      This is exactly the reason our EV has consumed so much of my driving. I don't want to fire up a cold diesel or gas engine just to drive 2 miles up to the store. It's arguably terrible for an engine. If I'm not driving at least 10 miles and don't need to do truck things, the truck stays parked.   Enter the EV. It's immediately heating or cooling the cabin as needed (heat pump). An engine doesn't need to warm up or be driven gently. I can tear off in it with ZERO guilt. Move the car 1/4 mile from store to store and not think "gee, I'm short-cycling a lukewarm engine".   It doesn't idle in a drive-through. Doesn't idle at stop lights. (OK, neither would the diesel, if I let stop-start have its way, but I don't).   Even moving it out of the garage to wash it... HA! It doesn't need to be started just to move 40 feet. I have cars that I will actually put in neutral and push (no start) in/out of the garage or shop if they absolutely HAVE to be moved. My nice Camaros.

      Transmission temperature 10speed with 3.0 LZO Duramax

      I traced the atf cooling system in my 1500 and it comes out of the transmission, into the bar/plate liquid/liquid heat exchanger, as stated above.  Then it crosses over to the external thermostat/bypass and then  to the aux cooler in front of the main radiator.  Hence, on this routing, the PPE thermostat bypass eliminator is an $85 piece of bling that does nothing for reducing atf temps on this truck.  I think I'll temporarily clamp a needle nose vise grip on the coolant feed hose to the bar/plate cooler and see how much the atf temp drops.  With the use of ULV trans fluid, I'm not convinced running the trans cooler than OEM spec is going to be detrimental to the life of the transmission.    I found this interesting on the Dana/Long site stating that they make transmission cooling/heating bar plate heat exchangers.  I worked with Dana/Long on a few projects when I was at the gas powered fun factory. https://www.dana.co.jp/downloads/PTG/Long/Dana_TOC_SpecSht.pdf  Bar plate heat exchangers are just a stack of stamped parallel path fluid channels, assembled and vacuum furnace brazed to make the final assembly.  Want more cooling/heating, just stack more plates until you run out of package space.   Anyway, thanks for the info, much appreciated.

      I have thought an EV might have some practical value in extending the life of the ICE members of ones fleet. Now....I'm convinced of it. I've been letting my better half access Raven (Mitsubishi Mirage) for her needs while Dizzy has been in the shop. Being the fuel freak I am and given the fact Raven is capable of over 60 mpg in clean air on a warm day I was taken back by the wife's ability to take a car that had used a half a tank of gas that to that point had returned a value of 57 mpg and return in with a decimating 51 mpg for that same tank in that same day in a 15 mile round trip of short hop errands and a stop in the drive through at Micky D's.  😱   Trust me on this. It would take the remainder of that tank driven on the highway to return that tank to just 54 mpg. This is not a Mitsubishi issue. This is an ICE issue that is magnified in vehicles capable of such high fuel economy values. On a percentage basis your 1500 does the same thing. Short hopping an ICE consumes a good deal more fuel and in doing so provides zero additional useable outputs. That entire volume of fuel is wasted in diluting the cylinder walls oil films, creating crankcase moisture and acid content and the resultant wear.    Enter the SLATE. All of that is avoided and the ICE's advantage in range and made useful at reduced wear for your ICE!   Kind'a cool.
