4WD Maintenance

[alwayz_yummy]

Guys, I need to clarify the following 4WD maintenance items:

1. Re-torque drive shaft bolt
- how is this done?

2. Replace rear differential oil
- a few months ago, I had the rear oil seal fixed * autotechnika then had the mechanic * speedyfix to top-up the "gear oil" near the front of the engine (he had to lift the car to access it btw). is this the rear differential oil or the transfer case oil?

3. Replace transfer case oil
- how is this different from the rear differential oil?

3. Replace front differential oil
- is this connected with the rear differential oil?

Thanks!

answer ko po:pero part-time 4wd po lite ko,e...pero ganun din naman, e..

1.kailangan re-torque, minsan or there come a time na lumuluwag ang bolts.. mahirap maghanap ng bolts nito pag naputol...

2.rear diff oil, easily na napapalitan yan, ilalim din... replace talaga every 5000/10000kms.. basta 90W yan or as stated sa manual.

3.transfer case oil, sa gitna po yan, hiwalay ang filler nyan sa a/t pero nakakabit yan sa a/t... same din ang oil ginagamit sa differentials 90w...or as stated..

4.front diff oil, same as rear diff...
