Maximln Posted April 4, 2008 Report Share Posted April 4, 2008 Can someone who has access to GM's TSB's, please post the contents of a specific TSB for me? The # is 030417004. It has to do with the replacement of the driveshaft. I would greatly appreciate it. Thanks, Max Link to comment Share on other sites More sharing options...
Logan Posted April 4, 2008 Report Share Posted April 4, 2008 This bulletin is being issued to revise the Propeller Shaft Replacement Procedure in the Driveline Axle sub-section of the Service Manual. Please replace the current information in the Service Manual with the following information. The following information has been updated within SI. If you are using a paper version of this Service Manual, please make a reference to this bulletin on the affected page. Propeller Shaft Replacement (Automatic Transmission) Notice: There is a first and second design of the propeller shaft coupler-to-transmission/differential flange bolts used on this vehicle. Ensure the second design propeller shaft coupler bolts are installed whenever the first design bolts are removed for service. The second design bolts must be installed in a specific orientation per the procedure. If the incorrect bolts or the second design bolts are installed improperly, damage to the propeller shaft coupler and/or the transmission may occur. • First design, fully threaded bolt (2). • Second design, shoulder bolt (1). Removal Procedure Raise and support vehicle. Refer to Lifting and Jacking the Vehicle in the General Information sub-section of the Service Manual, SI Document #813128. Remove the exhaust system. Refer to Exhaust System Replacement in the Engine Exhaust sub-section of the Service Manual, SI Document #783469. Important: Remove only the propeller shaft coupler-to-transmission flange bolts. Do NOT remove the coupler from the propeller shaft. Remove the propeller shaft coupler-to-transmission flange bolts (6), nuts (4) and washers (5). Important: Remove only the propeller shaft coupler-to-differential flange bolts. Do NOT remove the coupler from the propeller shaft. Remove the propeller shaft coupler-to-differential flange bolts (6), nuts (4) and washers (5). Support the propeller shaft at the support bearing. Remove the nuts (2) securing the support bearing to the vehicle underbody. Push the front propeller shaft (3) toward the rear of the vehicle in order to release the propeller shaft coupler (2) from the transmission flange (1). While holding the front propeller shaft (3), lower the support device under the propeller shaft support bearing. Remove the support bearing from the mounting studs. Pull the rear propeller shaft (1) forward to release the coupler (2) from the differential flange (3). Note the number and location of the shim packs between the support bearing mounting bracket and the underbody to ensure proper assembly. Remove the propeller shaft from the vehicle. Inspect the propeller shaft coupler for the following conditions: • Splitting of the coupler • Deep cracking. Minor superficial cracking of the coupler is acceptable • Looseness at the propeller shaft mounting bolts • Distorted or missing mounting bolt bushings If any of the above conditions are found, the propeller shaft requires replacement. Installation Procedure Using a clean shop towel, clean the following: • Differential flange centering pin • Transmission flange centering pin • Front propeller shaft centering bushing • Rear propeller shaft centering bushing Apply a small amount of lubricant, GM P/N 1051344 (Canadian P/N 993037), or equivalent, to the front and rear propeller shaft centering bushings. Inspect the propeller shaft to flange nuts (4), bolts (6) and washers (5). Replace if damaged or worn. Install the rear propeller shaft coupler (2) to the differential flange (3). Rest the support bearing on the support device. Important: If reusing the propeller shaft to flange nuts and bolts -- to ensure proper adhesion and fastener retention, the threads must be free of debris prior to the application of threadlocker. Thoroughly clean the threads using denatured alcohol, or equivalent, and allow to dry. Apply threadlocker, GM P/N 12345493 (Canadian P/N 10953488), or equivalent, to the propeller shaft to the flange bolt. Ensure that there are no gaps in the threadlocker along the length of the filled area of the bolt. Allow the threadlocker to cure approximately ten minutes before installation. Install the propeller shaft coupler-to-differential flange washers (5) to the propeller shaft coupler-to-differential flange bolts (6). Install the propeller shaft coupler-to-differential flange bolts (6) and washers (5) to the propeller shaft coupler (2) and differential flange (3).

Maximln Posted April 6, 2008 Author Report Share Posted April 6, 2008 Logan, Thank you very much for posting that for me. Here's my problem. My cousin has a 2003 CTS that about a year ago, one of the 3 bolts that holds the driveshaft to the flange came out causing damage to the driveshaft. The local dealer replaced the driveshaft and the bolt that was missing but not the flange (which the repair did not call for) under the GE warranty that she has. Last week, the nut that holds the flange to the output shaft on the transmission came off, stripping the output shift which now needs to be replaced. Originally, the dealer recommended replacing the transmission but the warranty company had declined the repair. I have been going back and forth with the warranty company and the dealership. The bottom line with the warranty company is per that TSB, when the dealership replaced the driveshaft, they were supposed to use the updated bolts but did not. The TSB clearly states that if the incorrect bolts are used, damage to the flange and or transmission may occur, which it did so the warranty company is still declining the repair, saying the damage was caused by the dealership using the incorrect bolts. The dealership is saying that their repair was only warranteed for 3 months or 4000 miles (it has been a little over 12 months and 12,000 miles) and if the repair they did was incorrect, something would have occurred sooner. Also, the fact that the incorrect bolts were used does not matter because the 3 bolts were still tight to the flange. There was no wear on the bolts or damage to them or to the flange. They are also saying that what needs to happen is that someone needs to authorize them to tear into the transmission because they are saying whatever happened inside caused the damage to the output shaft (they are assuming something mechanical failed inside the transmission). Even if they don't find anything wrong inside (I was playing devil's advocate) they still say they wouldn't be responsible because their repair could not have caused the problem. Again, the warranty company's standpoint is that they used the wrong bolts which caused the problem and will not authorize the repair or to allow inspection of the transmission. I appear to be at a standoff. Does anyone have an opinion on this? Thanks, Max Link to comment Share on other sites More sharing options...
Logan Posted April 6, 2008 Report Share Posted April 6, 2008 Big bang theory.. What came first, the chicken or the egg.. Nothing worse then insurance companies and warranty companies. Menance. We recently had Allstate in Texas claim they had speed data on a '96 Geo Tracker. Uuuu. That year did not have that data avaiable.. Consulted 2 other experts. They said make them lay down the crash they had. Turns out, Allstate had crap. Paid claim. Your case is a bit differnet. 2 companies pointing fingers at each other. Dont know your trans.. Most 'output' shafts, such as transmissions, the flange joints can be popped out without going into the trans. Maybe the dealer and the insurance company agree they will split the cost for new flange?

Maximln Posted April 6, 2008 Author Report Share Posted April 6, 2008 Thanks again Logan but the flange isn't the problem. The flange is fine. It is the output shaft where the flange attaches to that is stripped and needs to be replaced and according to the dealership, the output shaft runs the length of the transmission and has to be disassembled to access it. They have quoted my $2300 to disassemble the transmission and put it back together. I'm sure that's why the dealership nor the warranty company wants to assume liability.
