My knocking 8.1 2006 Suburban with 000,750 miles was being denied as a problem UNTIL I PROVED it was only 1 cylinder knocking at 1st start of day. One dealer who did not hear it said it sounded "normal" when "they started it in the A.M. Later in the day (4:30) P.M. when I went down and started it with the guy after per him it had not been started since early in that A.M. the service guy did hear the knock. He said that also is normal even though he did NOT hear it in the morning. SO no knock is normal and knocking is normal. All I could do was to look at him in disgust! The second dealer (place of purchase)heard the knock and would only check to see if there was a "bulletin". When there was not any bulletins they said too this was "normal". In frustration I disconnect 1 plug at a time and isolated the knock to ONLY 1 cylinder. It was the 3rd one back from the front on the passenger side. I described it in about 2 or 3 TYPED sentences and took it back to where I purchased it for the second time. Low and behold it did exactly what I said and when I said it would. After 30 seconds the knock started for about 30 more seconds. The "TECH" assistance people at GM I am told think possibly it is a wrist pin. I think they are going to put in a pressed pin. It's been at the dealer since last Monday May 15, 2006. They really did not want to inconvience me as this was going to take a while. I told them please KEEP IT/FIX IT I have another car. They are sticking to there story though in that if this does not cure knock it probably could be piston slapping due to design and they will "NOT" fix that and well you have 36,000 miles of guaranty. GM wonders why people buy japanese vehicles?????????? |

I have a 2006 Suburban less than a month old with 888 miles on it. It has from the beginning had a clunking, popping noise coming from under the front of the vehicle. It is getting worse. The dealer has kept the car for the past week. They said a Service Bulletin advised them to put washers in the front cross member. They did. Still clunking. Anybody have any experience with this problem? I asked them to remove the washers since they didn't help and therefore must not be needed. Clunking occurs only when stopping shifts the weight to the front of the vehicle. I feel that it is unsafe. I appreciate any suggestions.

I have read about problems with intermediate steering shafts in some other posts. Can somebody give me some details on this shaft. Where is it located? Exactly what is it? Is there more than one part to the steering shaft on 2006 Suburbans? Does the shaft have grease fitting or any other means to lubricate it? I have owned and worked on a bunch of cars but I have never came across a reference to an intermediate steering shaft. If there is a malfunction with the shaft, is it dangerous to drive the vehicle? Could it be causing the clunking noise on my new Suburban with only 888 miles on it. My dealer cannot seem to find the problem. I have described and given some details on it in a previous post. I welcome any thoughts and opinions on it. Thanks = = = Gary

I've looked at everything almost, and cannot seem to figure out why my 1983 Suburban Scottsdale won't start unless the Glow Plugs are cool. What would the solution be?

I have a 2001 Suburban that will not crank the first time. Sometimes I have to crank it 3 times before it starts. This happens more often when I am at or below a quarter tank of gas. I have been told that my fuel pump is going out. I do not want to spend over $200 for a fuel pump until I find out if this is what the problem is. How about a fuel pressure regulator? Could this cause the cranking problem? Thanks! |

I have a 2002 Suburban Z71 with 5.3 and 58K miles. I started noticing a loud metallic rattle/knocking that was coming from under the vehicle between the engine and trans. Loud at start-up then quieting down as car warmed up. Great oil pressure (60#) and does not sound like a rod knocking or the piston slap I've heard about. I stopped at a friends shop and he thought it was the catylic converter on the Y-pipe. He said something about the inside failing and coming loose then rattling around till it heats up. Sounds like it's a $600.00 part before the additional 4 Oxy-sensers. Has anyone heard of this before? No ECM lights on dash and lost of power. John |
