Replying to: mikefm58 (Sep 05, 2008 3:46 pm) What kind of "pressure test" did you do? If the compressor does not cycle on, then you won't have any high pressure on the High Side, and you won't have any low pressure on the Low Side. A pressure test is only meaningful if expressed in terms of pressure on the High Side and pressure on the Low Side, along with Ambient temperature and Vent temperature, and engine speed is helpful. Example of a usual reading: High Side=225 pounds, Low side=25 pounds, Ambient temperature=88 degrees fahrenheit, Vent temperature=46 degrees fahrenheit, engine speed 1500 rpm. |

Just got an oil change at the dealer. The inspection sheet said "transfer case and differential oil dirty, needs changing." This sounds like a way to lighten my wallet and fatten the dealers. Anyone ever have this service recommended? Aren't these sealed/closed systems? I need new tires. Looking at the Bridgestone Alenza to replace Michelin LTX. Much better ratings on Tirerack and a little cheaper. Anyone have these tires?

Replying to: lmacmil (Sep 23, 2008 12:01 pm) WHY do I need this work? Why don't you do this work when it's listed in the book or IS it listed in the book? If not listed in the book, again WHY do I need this work? Why is the transfer case and differential oil dirty? Is it time for it to be dirty? If not, why did it get dirty early? How dirty is it supposed to get before it needs changing. (Note for you; just because the oil is dirty does not mean it is bad and need changing, it only needs changing if it is starting to chemically break down or is very contaminated). That is why oils are generally changed at milage/time inetervals. I would not get those services, unless I really know I need them. If you really want to find out how good or how bad your oil is, you can send a sample of oil to an oil analysis company for a fee, and they will send you a full report with a full explaination. You can find these companies on the Internet. Just google "oil analysis". There is a company called Black something that says "Oil analysis can identify any problems developing in your engine long before they cause you an expensive headache. Or maybe you'd just like to get a good look at the microscopic wear your engine is producing. Can you run a fill of oil longer than 3000 miles? Are your oil and air filters doing a good job? Is your tranmission or differential oil holding up? We can answer these questions and more when you submit a sample of your engine oil for analysis."

Replying to: electricdesign (Sep 23, 2008 5:32 pm) The service writer had a brochure on his desk for brake fluid replacement. That's a service you won't find in the manual but is a good idea every few years because brake fluid absorbs water. They wanted $90!!! More than transmission fluid service. I'll buy a quart and do it myself. (He did say it probably didn't need to be done before 60K miles). |
