Volvo Troubleshooting Questions? Ask a Mechanic for Answers ASAP
Hi, my name is ***** ***** I will assist you. Do you happen to know what they used to lift the vehicle and check the tires? Was it done on a lift or was it done by using a hand jack?
No, I'm sorry I didn't catch that part. I am not familiar with this type of machine. It is conceivable that using a unit such as that and violently applying brake pressure could cause a differential to crack because it sounds like it would add stress that is not accounted for by the standard differential structure.
We would take the vehicle on a road test and then remove the wheels on a lift to visually inspect them. Are you saying that their machine will only operate 2 wheels at a time? If that is the case, it could have caused the rear differential to overheat as it would be spinning at a different speed than the front, and this could cause a case to crack.
I really think that this is something that would be the responsibility of the place that worked on it. If you didn't have any pre-existing issues with the car and suddenly when using their machine, the differential cracks and a piece falls off...it sounds like it is their problem. Either they used it incorrectly or it should not have been used on your car. I will say though that no matter what the case, an all time all wheel drive vehicle should never be operated on a device that will only operate 2 wheels at a time.
I am looking for something from volvo in my service manuals...give me a few moments
I'm sorry, I have thus far been unable to locate an actual bulletin delineating the fact that the all wheel drive should not be operated with 2 wheels only...I am sorry.
There is an option for full time all wheel drive. If your model says all wheel then that is what it is. It operates off of a viscous clutch between the rear drive shaft and the transfer case.
Hi, this is Josh checking in to see if you have any other questions.
I am sorry I don't have anything "official" that I can give you to take with you to court or wherever you are trying to use it. I wish I had something else to give you. I will opt out and see if someone else can help you
