Chevrolet Suburban owners have reported 18 problems related to differential unit (under the power train category).
Began hearing a "whining" noise under the vehicle. Noise was progressively louder at accelerated speeds. Left vehicle at local Chevrolet dealer (CA) who did an inspection and diagnosed a mechanical issue possibly with the differential [ref. Claim check 175]. Service writer stated estimated repair cost for an overhaul was $3,000 vs. Higher costs to replace with used or new differential. Service writer further indicated continued driving could cause further damage and added cost if axle was also affected. Decided to take vehicle to a recognized powertrain repair facility who determined (also with a drive test) that the differential was the problem and gave initial $1,200 estimate. Authorized repair. Final cost was $813 and includes 1 year full warranty. Now runs smooth / quiet when driving. Technician indicated that although fluid level was good (sealed at factory), a ring inside the differential was bad (had become pitted and could have caused further issues if unchecked. Changed out ring and bearings but all other components including casing were fine. Technician stated such wear is uncommon for a vehicle with only 126k miles and with no towing on factory tow package. Is this an annomily or are there other cases of bad parts in differential for this make / model? would like to discuss further with gm zone rep. But no response!!!.

The contact owns a 2011 Chevrolet Suburban. The contact stated that an abnormal and overpowering odor was present in the rear interior of the vehicle. The contact¿s four small children were asleep in the rear row seats and when called upon, did not awaken to respond. The contact exited the vehicle to inspect further and discovered the odor. Additionally, all four children had become asphyxiated by the fumes. Two of the four children were transported to the hospital where it was discovered that the children's asthma reacted to the overpowering odor, and were given medication for treatment. The vehicle was taken to one dealer where it was diagnosed that the rear differential fluid had overheated. The vehicle was taken to another dealer for the repairs where the technician stated that there was no failure and no repairs were performed. The contact also experienced rapid acceleration failure while sitting at a traffic stop. The contact stated that the vehicle was taken to the dealer ten times yet the failure was unable to be replicated each time. The manufacturer was notified of the failure. The vehicle was not repaired. The approximate failure mileage was 400 and the current mileage was 55,000. The VIN was not available.

The rear differential failed for the second time. Vehicle has 83000 miles. The last repair used after market parts. The parts company will not warrant claiming improper installation. Dealer claims design defect. This problem has been very frustrating. Same thing happened to my 1997 tahoe at 70k miles.

Driving on freeway along carpool lane when the car ahead of us stopped to move to the next lane and we all had to stop. I had a good distance from the vehicle in front of me when I hit the brakes. The brakes went all the way to the floor(literally) but still didn't stop until I crashed into the car in front of me. The abs brakes feels unusual. I also hear a clanking sound on the differential every time I have to decelerate and go back to normal speed or just moving from "park" to "reverse" or from "neutral" to "reverse".
This vehicle has been to a dealer for the 2nd time now to rebuild the front differential and it has only 22000 miles on it.
There is a grinding noise and a vibration coming from the bottom of the vehicle when slowing down. Took to dealer and dealer will replace the differentral. Please provide any further information. Ts.
The planetary gears failed in the transmission while driving in normal conditions with no load. The vehicle had been reported to the manufactures dealer while under warranty as having a violent hard shift after kickdown to pass another vehcile. The solution offered by the dealer was to disconnect the battery and reset the computer. This removed the initial problem for some time and then the shifting of the transmission from 1st to 2nd was very hard and jerky. The dealer would do nothing about it . Tricounty transmission showed me numerous parts from other Suburbans and tahoes which have the same original manufacturer failure. Gm will not accept responsibilty for this as they never do. They have a latent defect in the hardiness of the gear inside the transmission which causes teeth failure of the planetary gears. This could cause an accident if I had been driving in atlanta I-285 and the gears had failed in traffic. The transmission shop said this same problems applies to all 1998 thru 2002 transmissions for the chevy Suburbans and tahoes. Can you provide me with information on this matter. Thanks.

When vehicle's speed reached between 45-70 mph there was a grinding noise in the front end. The dealership found metal shavings in the front differential fluid. The dealership changed all the front end components in an attempt to correct the problem, but the problem still existed.
Differential serviced, causing rear end vibration. Mjs.
