Depending how you drive, I recommend changing diff lube about every three years or 30,000 miles. Hard driving at speed and long distances or in extremely hot places shortens this interval a bit, but then every two years is fine. (this isn't a dealer recommendation but my own observation after years in the business, seeing what works and what dosen't)

2000 VW Jetta manual trans - gear oil has never been changed. Will changing it now (145,000 miles) cause future trans problems? Also, should I change the Diff oil?


Changing the oil in a manual trans at higher mileage is not as potentially damaging as it can be in an automatic, since there is no pressure issues do deal with. So go for it, just be sure to use the exact gear oil the manufacturer recommends. It isn't worth cheaping-out here since the alternative costs can be staggering. The same is true with the differential. Be sure to use the right gear oil, and if it needs a limited slip additive or modifier, ensure that it is either already in the oil or that you get the right one and in the correct amount. Doing it wrong is worse that not doing the change at all.

When should you change the transmission fluid and filter in a 2005 Chevrolet trailblazer


The fluid should be changed at the 100K mark. The front and rear differential fluids should also be changed at that mileage. The transfer case fluid needs to be changed every 50K miles and only use GM Autotrak II gear oil.

When to change automatic transmission gear oil


The auto transaxle/differential fluid and filter should be changed every 30,000 miles or 24 months. The transaxle fluid and differential lubricant use the same Dextron III automatic transmission fluid. If you have a three speed automatic transaxle, the transaxle differential has a separate lubricant supply that should be checked every 15,000 miles or every 12 months. By the way........ see if there is a Half Price Books or other used book store in or near your town. I find used repair manuals like Hayes or Chiltons for $8.00 or less all the time. Hope this helps.

When I make a turn going 30-35 mph and the weight of the vehicle is at maximum force, I hear a clunk from underneath the vehicle. What could be producing this sound?


Try changing the gear oil in the rear axle. Be sure to add a Slip Differential Additive paste to it (Autozone sells the paste and the gear oil).
The noise is coming from the differential in the rear axle and you will hear it when the vehicle changes from one direction to the other. Drive a hard zigzag line in a vacated parking lot and you should hear it at each shift in direction.

Change the front axle gear oil also if it had never been down. Usual interval for both is 30,000 miles.

Gear oil change milage


Dodge recommends changing the gear oil every 15,000 miles. I personally do it every 30,000 miles and use the synthetic 75w-150. Also make sure you get the friction additive from a dealership so you dont get a chatter in the rear end due to the locking differential clutches.

Grease and differential oil inside left rear drum


Not that difficult, raise and support the rear of the truck and remove the wheels. Might as well replace both sides so you know you have new seals, remove the differential cover and drain the fluid. Once differential is opened and cleaned , remove the axle "C" clip that hold the axle in place and slide the axle out. Once the axle is out remove the wheel seal and clean around the area. This would be a good time to replace the wheel bearing too since you have access to them and there not that expensive. Install the new bearing and seal, note make sure you oiled the bearing and seal before installing it back and take care when installing the axle back in and "C: clip. Use RTV silicon gasket maker to seal the differential cover and wheels back on and lower. If your lazy like i am, you can drain the differential fluid and replace it with a 50/50 mix with gear oil and Lucas engine oil additives. That may stop the leak and get you a few more miles. You gear oil is (ford 75W-140) (Dana 80W-90)and the capacity is 2.6 liters and 3.5 liters if you have the 10.25 Ring gear. Good luck and hope this helps.

  3. Remove oil filler plug (2).
  4. Remove drain plug (1), and drain old oil.
  5. Apply sealant to thread of drain plug (1), and tighten it to specified torque.Tightening torque Differential oil drain plug a: 23 Nm (2.3 kg-m, 17.0 ft. lbs.)

Noise and vibration above 50 mph


Sounds like front differential or front drive axle issues. Check the front differential gear oil then take er' to the dealership before you end up spending a bunch of $. Most people change their oil frequently in the engine but forget about flushing the transmission fluid and changing oil in the front and rear differentials. I have three Ford 4X4s. Two which really get used hard. The 93 has 311K miles and still runs excellent. Trans and differentials get a fluid change every 25K miles and moble one synthetic engine oil changes every 5k miles.
