BodybyFisher Posted April 14, 2006 Report Share Posted April 14, 2006 If those are voids could that be a manufacturing defect? A few years ago I was at a NAPA parts store and they recommended against rotors made in China as they were seeing rotors with voids caused by manufacturing Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
Logan Posted April 14, 2006 Author Report Share Posted April 14, 2006 No...they are high spots. Equally spaced 5 places around the stub. Very strange. Every 72 degress? I marked the spots with a marker nearby...

BodybyFisher Posted April 14, 2006 Report Share Posted April 14, 2006 That us odd, was it leaking at the seal. Could this 'flange' have been cocking on acceleration causing these rises?

navion Posted April 14, 2006 Report Share Posted April 14, 2006 No...they are high spots. Equally spaced 5 places around the stub. Very strange. Every 72 degress? I marked the spots with a marker nearby... Logan, Just curious. Was the CV joint real stiff? Does the number of high spots on the stub equal the number of ball slots in the CV joint? I'm baffled, but possibly a stiff or realy worn CV joint could have caused the stub shaft to be side loaded at those points, causing the material transfer. What does the bearing in the transmission look like? I'll bet that the bearing is shot as well. Britt Britt Link to comment Share on other sites More sharing options...
Barry94 Posted April 15, 2006 Report Share Posted April 15, 2006 Here's something more to think about. Many, many years ago a friend had a Citation. (One of GMs first front drive vehicles) It had a problem of vibration around the 60-70 mph range. It was still under warranty, however the dealer could not find the problem. As time went on, it kept getting worse. One day he was visiting, we decided to check out everything in the front end. We found the problem. The drivers side axle was loose going into the trans axle. The bearing/bushing/case in the trans axle, where the axle enters, was worn and the axle was loose. At high speeds the axle would bow out at the inner CV joint (run in an elliptical fashion). This whipping effect caused the vibration. In seeing the metal transfer on your axle, I would think that the clearance, even with a new axle, would be beyond spec. The seal may prevent any leaks, however, with the additional clearance, you could get some mysterious vibrations.

Logan Posted April 15, 2006 Author Report Share Posted April 15, 2006 Ahhhhhh.... "The bearing/bushing/case in the trans axle, where the axle enters, was worn and the axle was loose. At high speeds the axle would bow out at the inner CV joint (run in an elliptical fashion). This whipping effect caused the vibration." I think this is exactly whats going on......this car is one of the wiggly ones. I can pry on the axle snub and it moves....arrrrgggg. The bearing is not available alone, you have to buy the transmission case extension and then some 'select' bearings for adjusment... messy work...

Logan Posted April 16, 2006 Author Report Share Posted April 16, 2006 Looks like hail damage to me! Yeah...going in Monday for the hail damage.....$4700..... Parts guy I know from Cadillac dealer called the other day....the used hood the insurance company 'recommened' also had hail damage....no good....he went ahead and ordered a new DTS (non hood oridiment!) hood.....another 500 on top of the 47. Fake DTS is getting sneaky. I'll deal with the trans after the body shop.
