Sounds like you have bad front wheel hub assemblies... google it, GM won't admit there is a HUGE problem with them, but there is. Just got back from a trip, had to replace the driver side front tire, wore to the steel belt. Went in for an alignment after new struts and whala, once again I have a bad assembly on the drivers side. This is the THIRD time I have replaced it in less than 2 years. Don't pay the dealer to do it. Get the part at the auto parts store and do it yourself. You'll save big bucks and it will wear out before the lifetime warranty so your next one will be free (if you install it yourself).
First start the engine and leave it in park and then check the level of transmission fluid on the dip stick (on the left at the very back of the engine).
Second check the integrity of the bolts holding the differential to the rear subframe. There are only three, two to the rear of the diff. in rubber mounted bushes and one on the left front vertically into a rubber cushioned washer mounting.
Third check the rubber flexible (dounut) assemblies immediately to the rear of the transmission output and in front of the differential input. The 6 bolts on each should be secure and there should be no cracks in the couplings. If they show signs of deterioration they are easy to replace.
A c/v joint is pretty much just a better universal joint in that it permits more flex range than a simple cross. (like a driveshaft universal) If it were possible to make a universal with eight caps instead of four, it would have similar range but would be impossible to install. Few suv's used in street applications have a true locking front differential as that makes steering very difficult on turns (outer wheel needs to turn faster than one on inside of turn as the outside "circle" is larger.) Most suv's have an "open" differential that permits easy turning. In reality most 4x4's only have two wheels driving the vehicle at any one time. Most optional setups have a positraction diff ( also known as a limited slip as it allows for slippage so wheels can change speed on turns)at the rear giving you a total of three wheels pushing. Off-road guys will often install a posi at the front, or a more radical approach is a "spool" that is 100% locked all the time, making street driving nearly impossible. Your front differential is "locked" or actually connected to the drivetrain by way of a transfer case that does exactly that...It transfers power to the differentials. On some it does this automatically by way of a viscous coupler inside the unit, or others that are engaged by the driver by either an electric servo or a direct lever. How far you turn the front wheels determines how much stress you are putting on the c/v joint. Most vehicles have a "stop" bolt somewhere on the suspension that stops the front end from turning further than it should. Most times the steering pump will begin to whine as you near the limit. C/v joints should last a very long time. Generally they fail because though they are internally designed very well, they are protected by a simple rubber boot. Once that boot is torn, split or otherwise compromised, road dirt enters and quickly destroys the joint. Once you find a split boot you can almost bet that the joint is in one stage or another of failure. The price of the boot is often about one third the price of a complete joint or even a replacement axle with joints installed. therefore changing just the boot is foolish. Symptoms of a bad joint are clicking binding or vibration from the area of the joint, but, sometimes vibration can be caused by wheel balance or a failed hub bearing. Making good diagnosis important.
It should be listed in the owners manual, but because of different oil cooler setups you may have to do the change yourself and add oil until the correct level is established..... for the first oil change. Most likely 7 liters,but start with 5,run the engine to fill the oil filter,let it sit for 5 mins and recheck and fill to full. Note the amount needed for next time.
the number 6 cylinder is located (if you are looking at it from the front of the car) it is on the left side third cylinder back from the front. you probally have a bad injector that is just dripping fuel into that cylinder.
