Is there a mechanic in the house ???

[aussiefarmer]

I am not sure how many mechinics we have on the forum ? I hope a few and this may become a helpful thread.

I can solve alot of mechinal and engineering problems but at the moment i need a diff expert to solve a puzzle for me ,
i have a intermittent howling in my rear end from my troubleshooting i believe its the pinion bearing as thats the only area with heat . I mate of mine recons i can replace the bearing without stripping the diff as it comes in from the front or tail shaft end , but i am not convinced as there would be nothing to keep the shaft and bearing from moving foward apart from the tail shaft .

So do we have some helpful mechinics onboard the forum ?

I was always told to add banana peels to the diff, but that may have been to take up the slack in the gears.

What type of vehicle is it aussiefarmer?

Checked oil in hope it was low or turning back to crude, but it looks good enough to spread on your toast :Y:

How much metal was on the sump plug?

Sounds like too much spicy food to me.

Have a friend with same model and trouble recently, even had trouble with fitting the bearing correctly, and he is a mechanic, I'l pick his brains again and pm you.

Havent drained it, only opened the level plug , theres zero lateral play in yoke so i dont think its chewing metal yet it only started 100ks ago and being intermittent its probably only been noisy for 2ks.

If the front pinion bearing is shot you are going to have metal through the oil and the rest of the diff as well. Unless you are experienced at setting up diffs a replacement centre from a reputable wrecker will be your best option, Dont forget to wash out the housing as well.

Diffs are easy to set up, all you need is a Dial Gauge with a magnetic base, you can buy them pretty cheap and as long as you have a big enough Vice then ya set.

just been making some calls and they have said the same thing
if you dont know what you are doing you could end up in a world of hurt better to get a replacement center ether reco or wreckers

When does it howl, on acceleration ...deceleration...all the time....above 100kms?

You can't replace the bearing without D&A the center, the pinion has to be removed before the bearing can be replaced, I've done pinion seals in diffs without D&A center but that was a sneaky oil leak on a certain model not for the average fixer
Which shouldn't be done as they have a squash collar in them and you can lock the diff up from over tightening

As far as the question goes AF no
Has it got oil in it, top it up with a thicker oil and see if it quietens, like a 120w
Don't put bananas in it

what about saw dust ] ] ]

Thats what i was after :Y: i said to my mate " you mean replacing the seal ?" But he reckoned the bearing from the front , i thought he must be a magician to get the inner bearing collar off the pinion whilst it was in the housing :lol:
I will be fixing my center as its only got 200,000ks on it and the backlash feels good and doesnt whine at all :Y: plus i rather the devil i know than a random 2nd hander.
Might get some qoutes because i hate working on cars as i do more than plenty on tractors, headers and other machinery.

Sawdust is for the transmission. Lol
I've actual seen it.

 

[7.62marksman]

There might be a model the bearing will fall out but I've never seen one :lol:
don't know I'd like to own the vehicle it had been done to though :lol: 2000kms and it starts leaking oil :lol:
