  1. On RDU failure. It looks like the pinion bearings are failing due to fluid break-down due

    to excessive heat. It is tough to figure out if they do light weight fluids for EPA crap.

    Bearing clearance on rotating parts has not changed. Clutch pack clearances are the same.

    Hence, the tighter clearances B.S. that is fed to us, is not a starter nor valid! 

     

    Before the recent push to maximize fuel economy, lower emissions especially CO2, a heavier 

    weight differential fluid ie. 75-140 etc. was called for for heavy duty service or towing.

    Remember, Domestic manufactures sell new vehicles. The faster your new pride and joy wears

    out, the faster the bastards can sell you a new one.

  2. You might look at the battery terminals replace as nessary. A bad chassis ground or the PLUS side

    of the battery to the power distribution box would cause the problem you described. Those originate

    at the battery in most cases. Your charging system appears to good, according to your readings.

     

    As a side note, take your high RPM readings with ALL of the electrical load. A/C on ,fan on high,

    bright lights, etc. or 1/2 volt or so above the resting voltage about 12.8 volts.

  3. If your fuel additive does not have PEA in it, your, shall we say, "urinating into the wind".

    As far as oil, I would point you to Lake Speed jr.'s video on Valvoline's Protect and Restore engine oil.

    To go deeper, find his comparisons of oil tests too.  

     

    Did not realize there was a pun till I proof read it.

  4. What brand of tires and what is the DOT code on the tire? It appears so

    one likes to drive what some would consider a little "sporty". The shoulder wear (both sides)

    indicates where the steel belt ends. If it was a toe problem, the edges of all of the tread

    blocks would have a feathered edge on one side. But, the pics indicate small chunks are being shed while

    at high steering angles.

     

    In the top image it appears that a little extra wear is indicated by the right side being a little

    more worn than the left. That would indicate about half a degree of extra camber to that side, providing

    that is about 12 K miles in normal conditions on that tire.

  5. My 1st. plan expires @75K miles/ 2028. I just did a RDU service and

    discovered metallic glitteries! I am not as mobile as I once was. Do we

    keep the problem and extend the ESP or swap it out for an Exploder ST?

     

    I contact my guy with my wallet wide open! He told me keep your $$$

    till 73K miles or 6 months before expiration date to renew. Hang onto your money!!!

    After that experience as well as other folks experience,  I why people from across

    the US do some driving.

  6. Hate to tell you this but, sounds like a U-Joint or the Carrier bearing. Look

    closely at the u-joint's cups to see if any rust is evident. If so, that is what

    is left of the rollers due to "Fretting Corrosion". Also it is the "Down Fall" and

    the waster of several hours of grief, "It could not be _________ as it is new part"!

     

    If you decide to do the u-joints, spray paint the parts so you assemble them

    back in the same position. Even some times this does not work and a vibration

    is induced. Sometimes it can be fixed by rotating the assembly 180 degrees.

    Else the drive shaft shop. (do they still exist)?

  7. I see this an old thread but, a continuing problem for some as well as someone's future.

     

    Water on the heater core is causing this problem. So, typically,the heater core is leaking or

    the A/C drain is plugged up. Water intrusion from a puddle or rain, might enter via the A/C or heater

    lines entry points of the Firewall.(Rare) Last but not least the A/C drain lines.

     

    If it is the Heater Core the fog on the windows will taste sweet else it's the drain line probably.

  8. Check the anti-rattle clips and/or pad shims. The "hum noise" you hear is the pad "rattling"

    from "kick-back" of the pad due to very small high spots on the rotor. In the past, I've cured

    disc-brake pull as well as noise by switching pads side to side as screwy as that sounds!

    Re-lube the mounts and refinish the rotors (sand them with a sanding disc) and if all fails,

    change to a different pad material.

     

    Sometimes the combination of parts do not favor a driver.
