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

UNGAS, ugong ba yung naririnig mo sa tranny and diff mo? hindi kaya yung gears na ang may ugong? kung gears, even a 140 gear oil will not solve the noise.

isa lang ang kilala kong magaling mag-rebuild ng tranny/diff gears in the Philippines, i.e., Precision (i think ISO 9000 certified sila). They can even ceramic coat your gears for durability and reduction in running temperature. Precision is a certified machine shop of all BMW and Mercedes dealerships. Medyo pricey but with guaranteed quality.

just my 2 cents though! :wink:

woodfire::: Nagpalit muna ako ng axle bearings and repacked it with high temp grease. I will still try to evaluate it baka sa bearings nanggaling yung sound. The old bearings showed signs of wear and it produced a tarnish color that indicated bearing overheat. BTW, changed all bearings and oil seals on 4 corners thanks to the warm and hospitable service station of chieffy. (may free miryenda pa!) :mrgreen:

Hehehe, I guess you know VW Precision Automotive. :D I know that machine shop too, especially the owner Mr. A. Inducil. Dun ko rin po dinala nung masira yung engine ni ser happiman. But I know one more shop that deals with tranny and diff gears, Gerco Machine Shop in QC.

Ako I just had my gear oil changed. 90 sa trans at 140 both sa front and rear differentials. So far so good.

roydok::: Di po ba nag-iingay sa diffs ang 140 grade? I haven't change my oils yet. :|

Ungas,

Baka naman yung ugong ng mud terrain tires naririnig mo? Your dunlop M/T tires are one of the most quiet Mud tires around but thaey still make a whinning bad diff sound......

wolfpack::: I heard the noise even during the A/T tires that I used before.

ano kaya problema nung van namin kapag nasa mataas na gear kapag nag engine brake ka for example sa humps or sa kalsada na pababa may tumutunog sa ilalim banda sa may gitna pero kapag nag neutral ka agad wala naman
ano kaya yon? differential na kaya ang may problema? or kailangan na ng bagong gear oil?

My primary guess would have to be your center bearing holding the propeller shaft. Baka po natuyuan ng grasa ito. Better have your suking gasoline station grease all the moving parts and greasable joints. Pag hindi nawala ang ingay malamang sa bungo na ang tama or it could also be your wheel bearings. :D
