The vehicle (where a record says)

A record is under an engine, a drive or a series only where it says so: the characters of the vehicle identification number filed with a complaint, its text, or what its document says it applies to. A record that does not say is kept as "not stated". The filed numbers and the documents do not tell 4WD from AWD.

Common on this vehicle:Warning lightNoiseLeakMisfire or rough idleVibration or shudderAir conditioning or heaterReduced brakingCorrosion or rust

Record by record

72 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.

How it is said to have ended

  • says it did not fix it2
  • result not stated4

A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

Known issuesSingle-cylinder misfire (P0300-P0308) and/or chirp, squeak or tick at camshaft speed: worn cam lobe / lifter, valve or valve spring2

  1. Manufacturer communication2000–2006 GMC YUKON DENALI ・ 2017-08-15(2 earlier editions of this document folded here)

    Engine Misfire and Service Engine Soon Lamp Information

    1. 1Fault

      • With the SES light on, a P0300-P0308 DTC is found with misfires counting on a single cylinder, which may or may not be felt.
      • The noise may be described as a chirp, squeak, squeal or tick and may increase off of idle.

    2. 2Finding the cause

      Possible causes

      • A worn cam lobe on this engine family generally makes a consistent chirp, squeak, squeal or tick at camshaft speed and/or a misfire with a P0300-P0308 DTC.

      Steps to confirm (in the document’s order)

      1. Press on the rocker arms with a wooden hammer handle while the noise is present; if pressing the valve side of a rocker changes the noise, a lifter and/or cam lobe concern on that cylinder is most likely.
      2. Measure cam lobe lift at the push rod side of the rocker arm; it will differ from the SI specification but should be similar to the other rockers on the same bank.
      3. A bore scope or pen light may help when inspecting the cam lobes through the lifter bores.
      4. A good sign of a sticking valve is that misfires keep counting during an aggressive deceleration with engine braking.
      5. The Cylinder Leakage Test in SI should typically isolate valve leakage by showing excessive leakage past an intake or exhaust valve compared with the others.
      1 more points

    3. 3Correction

      Repair

      1. If a worn cam lobe or lifter roller is found, replace the camshaft and all lifters per SI, plus the plastic lifter guide for the affected lifter (for the 2010 model year, all the plastic lifter guides).
      2. If force is needed to tap the valve off its seat, there is excessive carbon build up, which may be repaired by decarboning the engine.

Known issuesGrind / ratchet noise when shifting into Park in 4LO (characteristic)1

  1. Manufacturer communication2000–2006 GMC YUKON DENALI ・ 2018-08-20

    Light Duty Trucks: Grinding Noise in Park with 4WD Low

    1. 1Fault

      • Light duty trucks with automatic transmission and 4 wheel drive may make a grinding/ratcheting noise when the transmission is shifted into park while the transfer case is in 4 wheel drive low (4LO) range.
      • The grind/ratchet noise lasts approximately one second.

    2. 2Finding the cause

      Possible causes

      • When the transmission is shifted from drive or reverse into park with the transfer case in 4LO, the driveline unloads and turns the propeller shaft approximately 1/8 of a turn.
      • The gear reduction in the transfer case makes the transmission output shaft turn faster than the parking pawl will hold, so the parking pawl grinds/ratchets until the output shaft stops.

    3. 3Correction

      Caution

      • This should be considered characteristic of 4 wheel drive vehicles operated in 4LO.
      • Replacing transmission, transfer case and/or driveline components will not resolve the concern; shifting into park with the transfer case in the 4HI or 2HI range is recommended.

    Remedy
    Tire Scrub Noise On Low Speed Turns Owners of some 1999-2005 Full Size Trucks and Utilities may experience tire scrub noise on low speed turns (parking lot maneuvers). The steering rod (centerlink) can be installed backwards on all trucks and utilities with recirculating ball type steering that do not use a steering dampener. The idler and pitman attaching holes are tapered in only one direction. To determine the correct installation of the steering rod, compare to a like vehicle. In a correct installation, the steering rod should curve to the rear, outboard of idler/pitman attachment holes and inboard of the inner tie rods. With the steering rod installed incorrectly, the curved portion of the rod between the idler/pitman holes and inner tie rods curves toward the front of the vehicle. Remove and correctly reinstall the steering rod (centerlink).

    Technical Bulletin Revision for 2013-2014 Model Years

    1. 1Fault

      • On automatic transmission vehicles, a clunk noise when shifting between Park and Drive, Park and Reverse, or Drive and Reverse.
      • A clunk noise while driving when the accelerator is quickly depressed and then released.

    2. 2Finding the cause

      Possible causes

      • Gear clearance or freeplay (lash) can produce a clunk whenever a gear is loaded and unloaded quickly or the direction of rotation is reversed.
      • In a 4-wheel drive vehicle the transfer case gears and their clearances add freeplay on top of that from the rear axle gears, universal joints and transmission.

      Steps to confirm (in the document’s order)

      • Compare the complaint vehicle with a like vehicle; if the results are the same, it is a normal condition.

    3. 3Correction

      Caution

      • Because every driveline component has some lash by design, changing driveline components may not reduce the lash satisfactorily.
      • The clunk noise does not adversely affect durability or performance.
      • Do not confuse this with the clunk at stop or from launch that is handled by cleaning/lubricating the rear propshaft slip yoke splines (Corporate Bulletin Number 09-04-21-003D or later).
