Oil Analysis Comments:
No problems found in this front axle sample. In fact we're happy to see that the oil is still in place - it can easily be run longer. Our universal averages show typical wear levels for a Dana 44 axle after about 47K miles on the oil. Your metals are lower than average, so feel free to add 20K miles to this fill before you resample. The TAN reading of 2.1 shows little acidity. Great report

wix kits are the cheapest. They are around $10 each plus shipping/handling at Rockauto.com

Blackstone and Oil Analyzers are around $30 each + shipping

Dyson analysis is around $100 bucks I think...

Heck for the cost of sampling, I just change the gear oil. If you changed it every 3 years you wouldn't have to worry about it, and since it's so easy to change anyway. cheers
