GEAR OIL: What do you use? 90 or 140 grade

[ARB]

yes may diff locks ang patrol, suggest lang maybe better ang castrol since it is for lsd and it may have additives that is good for lockers also.

we usually extend the breathers for water fording so that water will not enter thru it.

di ba auto locking hubs ang front nang patrol that can be manually locked for hard off roading? so if you use it on 2wd the front diffs dont spin maybe the noise is coming form somewhere else. just a thought.

So far hindi pa naman ako pinasukan ng tubig while water fording, I could assume it is still effective sa stock place nya.

Yep, hybrid locks ito. Auto and manual lock ang function. I was thinking where could the sound come from, baka pa repack ko na rin muna yung front bearings ko. Pero pag mainit na and matagal na tumatakbo nawawala kasi yung sound kaya di ko matukoy kung san galing. Normally, pag natuyuan ng grease ang bearings consistent ang sound, lalo pa lumalakas pag matagal na tumatakbo ang sasakyan.

Ungas,
The Y60 service manual specifies SAE90 or 75w90 or 80w90 for temps below 40C for frt and rr diffs(GL5), manual tranny and transfer(GL4). Think 140 is too thick which may hasten wear when diffs are cold.

Have you considered using synthetic gear oil?- gives smoother shifts.

What's the brand of your other diesel, isuzu uses engine oil on their manual trannies.

I use a GL5 gear oil on my rear differential. I think its a SAE90. GL5 for LSD equipped rigs. Penn something I think yung brand, gawa sa U.S. Php 250+ per liter. 1.8 liters needed sa likod.:lol:

[afrasay]

mas madaling mag flow ang 90 compared to 140. pag medyo old na ang diffs. pede na yan 140, although medyo mabigat dalhin pag cold ang weather.

I just remembered what sounds it makes, para ba syang sound ng kotse running in reverse at 10km/h. I knew the manual says SAE 90, but I already change the gear oils twice and it still produces the same sound again and again.

No I haven't tried synthetic gear oils, do you have any ideas where I could purchase it?

The other diesel ride is a 1998 Hyundai Starex, which has the same symptoms of hard engaging in 2nd gear during early morning runs.

i rode many patrols already i noticed a sound when in first gear only, does your patrol have the same sound?

[jackaroo]

Synthetic gear oils available locally:
Mobilube SHC 75w90 or Mobil 1 synth gear oil 75w90- P500/L
Redline MTL90 or 75w90 gear oil- P600/qt
I'm using redline on both transm and rear diff, no problems with noise or sticky shifts. Plan to use Mobilube SHC on next vehicle.

Have you checked cross-joints on front prop shafts?

Ungas,

Halos pareho ng Pajero ang tranny ng Starex. Mahirap talaga 2nd gear niyan sa umaga. hehehe.

Nope, the sound usually came in 2nd or 3rd gear running at 50-60km/h.

Take noted of your choices, thanks! Where could I purchase them?

I usually have all the prop shafts checked for any bad signs of vibration monthly. Even the common greasable tips.

Ganun ba talaga yan? Hmmm... pano naman yung Safari ganun din ang sakit?
