Hello, thank you for writing in. The power steering pump should not need to be bled. When the last pump was changed air was introduced into the system. The air is likely not working itself out. If the bubbling becomes...
Hi - the first task is to check the transmission fluid level to make sure it has adequate and good condition fluid - proper level, red and clear (as opposed to dark and brown/black). If the fluid is dark and...
This may be a result of low transmission fluid or potentially a faulty transmission control module. A faulty transmission control module may cause a delay in acceleration or erratic shifting of gears. The transmission control module has various sensors such...
Hi there - I suspect your vibration behavior is caused by driveshaft problems with one or both of the driveshafts. This may be simply an out-of-balance problem, or a mis-aligned or bent driveshaft issue. You should have eliminated bent wheels...
Hi there. It is possible for oil to soak into electrical components of an alternator and cause it to fail prematurely. If the oil leak still exists after completing the recent valve cover gasket changed, it's possible that the source...
As the codes indicate, this means there is a lean fuel condition which may be caused by a lack of fuel supply or in some cases, a vacuum leak as you describe near the cold air intake. When a vacuum...
Hello. If you have oil coming from the charge tube at the intercooler then the area needs to be cleaned and checked for further leakage. If there is oil in that area then it is typically due to a turbo...
It is possible that your fuel pump would be getting weak. Often times if the fuel level is run low many times, this can cause the fuel pump to overheat. If the fuel pump overheats, this can cause it...
Hi there: Damage to the flywheel on a 2007 Chevrolet Trailblazer is highly unlikely unless you're experiencing serious transmission, acceleration or shifting issues. In most cases, a knocking sound will be caused by internal engine components that are experiencing lack...
Hello there, thank you for asking about your 2006 GMC Sierra 1500HD. It sounds like the transmission is slipping. Replacing or rebuilding the transmission is likely the cure. To be certain, I suggest having a professional inspect your vehicle firsthand....
Your car is equipped with an Advanced Traction and Stability Control system called AdvanceTrac®. If the AdvanceTrac® light comes on in your dash, it means one of two things: It comes on when you first crank the engine while...
Hi there You should have the computer Check Engine Light scanned by a mechanic. Once the codes are received and the pinpoint test is completed, you should have a diagnosis of the failed component. A lot of times a code...
Hello. Thanks for writing in about your Mercedes-Benz ML350. It is recommended to replace it if the rotor surface is worn, damaged, or is too thin. Typically I would always recommend replacing the rotors anytime the pads are changed. By...
I would recommend looking in your vehicle's owner's manual for this particular information. This is not something that would be the same on all or even many vehicles. Each vehicle will have a specific way for doing something like this....
Hi Eric. Sorry to hear this happened to you. Oil pan's bolts don't typically "just strip". It's typically always due to either over tightening, or cross threading. The problem is trying to prove whether it occurred with the previous oil...
It sounds like what you are describing may be related to a faulty starter relay. The starter relay directs power from the battery to the starter solenoid which then engages the starter when you turn the key. When this is...
It is possible that you may have a lug nut loose. However, if this were the case, the wheel would wobble at all speeds and not just when braking. This may be more likely related to a warped brake rotor....
Without knowing what is causing the failures in different systems it would not be safe to say it is safe to drive. You need to have the ABS and other systems scanned to get failure codes and have those codes...
Hello - these two components are unrelated. The principle function of the secondary battery is as a backup for the primary battery - for the Sensotronic Brake System, which uses electronic pumps for brake pressure to each wheel - not...
If the key is turning to the “lock” position and won’t come out, the lock cylinder is faulty. If it is not turning all the way back, there is a solenoid that is malfunctioning in the steering column. That solenoid...
Hello. If your hood sensor indicator is on then that is a sign that the hood is either open, or that there is an issue with the hood sensor. If the sensor is faulty I would recommend repairing the issue...
Hi There, This can be caused by a loose battery cable which is often times the problem. Try checking to be sure they are connected properly. Also, there is a sensor that has 3 small wires running to it that...
