Replying to: shiftless (May 22, 2006 5:22 pm) Not sure on the Goodyears but if your concern is a smooth, quiet ride I can assure you the Michelins fit the bill. Replies to this message: bigfur (May 27, 2006 6:42 am)

Replying to: obyone (May 26, 2006 3:56 am) Birdgestone Dualer A/T revo. Have them on my 01 'rado and love them. Quiet but still have plenty of grip in the snow here in minnesota. Also should note that my tires are 285, no lift kit and they still fit, barely. Brother in law has over 50K miles on his and they are only at about half tread life gone.

Replying to: titojermaine (May 23, 2006 5:21 pm) sounds like typical gm power window motors. I'm on my third motor in wife's pontiac grand prix. the contact/brushes wear and the motor can stop in spot with a gap. no much to do but change out the motor. i found a cheap source for motors, http://www.powerupauto.com. Good luck. If you call, the guy can answer a lot of questions.

2003 GMC 1500HD, 6.0 L; I am having an intermitent problem with the speedometer. It will often display much higher than actual speed. When stopped the gauge will read 20 or 30 mph. It comes and goes. I've been told that everything is electronic now. It sounds like it must be the gauge. Any thoughts? Do you have to replace just the speedometer or the whole gauge cluster?

#1436 of 1492 GMC Sierra Distributor Cap by wolfsroad68 Jun 05, 2006 (10:25 am)
Has anyone found a tool that helps in changing the distributor cap, or any other easy way to change the cap for that matter?   I have a 1998 Sierra 3500 Dually 4wd. Last time I changed the distributor cap and rotor it was an 8 - 10 hour thing, because the cap is under the intake manifold so it is very difficult to tighten one of the cap's screws.

Replying to: noobie1 (Nov 30, 2005 9:32 am) Hello fellow GM owners,     I finally found something to post on here. The "piston slap" issue is really a load of crap. Dealers say it does it on start up and goes away, but I have noticed while driving the valves rattle like you have bad gas.     The knocking you hear is more than likely the roller lifters with no oil at start up. The excuse piston slap is used is how the design of the engine and where the lifters are placed in the engine. They are held in place with in a grouping of 4 in a container that is bolted to the block. Due to the design the opening is large enough to amplify any engine noise near the pistons and the heads are bolted directly on top of the lifter gallies making it difficult to make this repair.    I pulled the valve cover and ran the motor with little or no oil coming thru the pushrods on the lifters. I also have found out that the oil pumps can fail with no warning and have ran as low as 6psi at idle which the dealer says is normal.    I am in the process of replacing the oil pump and lifters and hopefully will remedy my situation. It has not burned oil, like I have read on sites where 2-4 quarts of oil between oil changes is normal by dealer or GM customer service standards but it is not normal, I have had several GM's in the past and 1 quart or less in 3-5k was normal.    I really love my truck and yes GM has got problems but they better get their stuff together and take care of the customer instead of being in denial or they will not have customers.
#1438 of 1492 HARMONIC VIBRATION 2002 GMC C/K1500 by jf3761 Jun 20, 2006 (5:49 pm)
I have a 2002 GMC Denali PU 6.0L W/Quad Steering. Between 30-40MPH I experience a vibration noice (sounds like a heat shield vibrating maybe) When the vibration begins and I hold my speed steady, the vibration will not go away. I do not lose power or feel any change in vehicle handling. It is just anoying. Does anybody have any clues Replies to this message: geo9 (Jun 20, 2006 10:48 pm) jf3761 (Jun 21, 2006 2:43 pm)

Replying to: jf3761 (Jun 20, 2006 5:49 pm) JF..........Since you live in snow and salt country and your truck is a 02 I am betting on a loose heat sheild on your cat(s). Those cheap spot welds just break/rust off thus causing the vibration(s). Try driving a few wood wedges between the cat and muffler and see if it cures your problem.

#1440 of 1492 Loud Blower Motor by kimble989 Jun 21, 2006 (6:32 am)
Guys: My father has an 2000' model GMC Sierra with a 5.3L/V8 Vortec Engine. Nice truck with somewhere in the neighborhood of 35,000miles. Lately his blower motor is very loud when using the heater/ac/vent. I told him I would write on here and see if any one had any ideas of why this is. Just the blower motor going bad? or can something else cause this? Thanks guys, kimble989
