OldCadTech Posted May 10, 2017 Report Share Posted May 10, 2017 The knock noise sounds like a bad tri-pot joint ( inner most joint of the axle ). Check with the suspension loaded. With a long pry bar, pry up on the axle shaft. There should be very little if any movement of the shaft.

OldCadTech Posted May 10, 2017 Report Share Posted May 10, 2017 No, but when you change the hub the axle will be easy to change. THERE IS ALWAYS ENOUGH TIME TO DO THE JOB RIGHT - THERE IS NEVER ENOUGH TIME TO DO THE JOB AGAIN !!! Link to comment Share on other sites More sharing options...

Göran W Posted May 12, 2017 Author Report Share Posted May 12, 2017 Nope! We are all wrong..... The knocking is present when car isn´t moving! Just by turning the wheel. Don´t think that is possible for bearing OR tripod? Any new ideas? Link to comment Share on other sites More sharing options...
BodybyFisher Posted May 12, 2017 Report Share Posted May 12, 2017 Haha.......wait, this was your diagnosis There is "knock, knock, knock" at low speed when turning (L or R). Can be heard and felt in stearingwheel..... Logically, @OldCadTech and I responded per your symptom. Sooooo, we were right!!!

OldCadTech Posted May 12, 2017 Report Share Posted May 12, 2017 The 2002 4T80-E transmission was infamous for the left ( drivers ) side 3rd clutch bushing wear. My STS has it , when it is started cold the axle shaft and tri-pot joint will "wobble" severely and it eventually gets bad enough that the output shaft seal will leak, especially when cold in reverse. With the vehicle in park, engine at idle turn the wheels to full left and watch the left axle shaft. If you lift the left front wheel off the ground, engine off, grab the tire at 3 and 9 o'clock and push-pull if you hear the "clunky/knock" noise check the tie-rod ends for excessive wear. @BodybyFisher is never wrong, I on the other hand have been wrong twice BUT I divorced both of them......

Göran W Posted May 12, 2017 Author Report Share Posted May 12, 2017 I know...... Happens all the time. About output shaft seal: The knock happens on turning the wheel. Cold or hot makes no difference. Reverse, Park or Drive makes no difference. Also no difference how far I´ve turned the wheel. Link to comment Share on other sites More sharing options...

Turning the wheel was so you could look at the axle to see if it was moving. Having the wheel off the ground was so you could move it by hand and watch the tie-rod end for movement.

BodybyFisher Posted May 17, 2017 Report Share Posted May 17, 2017 Low battery or bad /corroded connection at the battery. If you left the door open for a long time battery will drain if car is not being driven often especially 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 May 18, 2017 Report Share Posted May 18, 2017 There were several TSBs for the clunk. One had you use a different grease..it came in a repair kit....that proved to be a short lived solution. On mine...I replace the shaft with a used one. There is a newer shaft available....not sure if it still available or not. Here is a copy of one of the TSBs from Google related to the clunk. Not sure if it's the latest one. It was a common issue at the time and it certainly was not just a Cadillac and Pontiac problem. Looking at the TSB....it says the newer design is a double D.....pretty sure my noisy one was a double D design....be sure to check to see if there is a newer bulletin. This one is dated 2006. TSB#06-02-35-010 - (05/09/2006) Quote: Models: 2001-2004 Cadillac Seville -- with RPO JL4 2001-2003 Oldsmobile Aurora 2000-2005 Pontiac Bonneville Attention: This bulletin ONLY applies to the above listed vehicles. All other cars with a similar condition should refer to Corporate Bulletin Number 01-02-32-001G. -------------------------------------------------------------------------------- Condition Some customers may comment on a clunk type noise coming from the front of the vehicle while driving during a turning maneuver. This condition may also be felt through the steering wheel when the vehicle is stationary and the wheel is rotated from steering stop to steering stop. Some vehicles may only exhibit the noise once for every 360° of wheel rotation. On all other vehicles, this clunk noise will be noticed during low speed acceleration or deceleration, typically in light turns of the steering wheel. Cause This condition may be caused by inadequate lubrication of the steering intermediate shaft which results in a "slip stick" condition possibly resulting in the clunk noise. Diagnostic Tip Important: This condition is commonly misdiagnosed as originating in the steering gear and has resulted in the replacement of numerous steering gears without correcting the concern. Engineering Investigation shows that numerous steering gears have been misdiagnosed and replaced. The investigations shows that if the technician incorrectly diagnoses the steering gear as the cause of the noise and/or clunk during replacement of the steering gear, the technician may stroke and/or cycle the I-shaft, distributing the original grease in the I-shaft. This distribution of the original I-shaft grease temporarily may eliminate the I-shaft clunk so that the technician believes the noise and/or clunk is corrected with the steering gear replacement and returns the vehicle to the customer. After the customer drives the vehicles for several miles and dissipates the original grease, the noise may return. Attempt to duplicate the customer's concern and isolate the I-shaft by following the procedure below: Locate a large area (parking lot) where the vehicle can be turned in a tight circle. Turn the steering wheel to the right and/or left all the way to the steering lock, then off the steering lock a 1/4 turn. Drive the vehicle approximately 5 km/h (3 mph) in a circle, preferably over rough pavement or seams on the road surface. If a clunk is felt in the steering wheel, the MOST likely cause is the I-shaft - not the steering gear. Continue with the correction. Correction Important: The replacement steering intermediate shaft is physically different in appearance than the original. However, the vehicle's ride performance will not be affected. Replace the original concentric style steering shaft with P/N 26068295, a Double "D" design. Refer to Intermediate Steering Shaft Replacement in SI.
