Pajero Owners Club of South Africa

Please help

I have a 2011 Pajero GLX (diesel auto) that makes a noise under power (acceleration ) from the rear that we only assume comes from the diff area.

Any one that has experienced and solved this ?

Any help or information would be appreciated

Thanks

More detail:

I start noticing a noise and vibration coming from the diff area about 4 months ago

After taking the Pajero to a couple of specialists, the rear diff were replaced and both side shafts were serviced, but still no improvement
Then, both prop shafts were taken of and inspected and the culprit was the rear prop shaft needed 2 new cv joints.

After wheel bearings were also checked we still heard 'the noise' from the rear that were not the same noise as before the 'operation'

I also removed the catalytic converter a couple of months ago

Could it be that the increased noise from removing the cat were overshadowed by the vibration in the prop-shaft and now it is only the noise from the exhaust that is heard ?

As the only thing that has been changed and not reverted back is the Catylitic Converter.

All else has been checked over and overhauled.

Resonance is often a bugger. Just the removal of the CC could create different harmonics which become a "noise"

Thanks Mitsu Fan,

I believe you are right !

The sound also change and becomes 'softer' as the Pajero warms up

Hi Guys

I am driving my third Pajero and use my car every day for my work. Sold both my former Pajeros with more that 500 000 km's on the clock and I am currently driving a 2012 GLS bought two months ago.

I know these cars from top to bottom and to cut a long story short:

The CV joint at the diff end at the right rear end seized. To the amazement of the Pajero gurus it has never happened before...
No parts available in South Africa and if they have to order from overseas it will cost me R35 000 and I will have to wait 6 - 8 weeks....
No engineering place can rebuild it. I am stuck in East London and I live in the Western Cape.
I urgently need any assistance if you guys may know where we could find a second hand complete side shaft.
The dealership in East London have searched everywhere and cannot find a second hand one.
If we cannot find one it will result in me having to buy another car after two months.

Please, if you guys can suggest any place where we can search for a second hand complete shaft, I would really really appreciate it.
My number is 082 220 3406
Kind regards

Why don’t you remove both the rear side shafts, place the super select into 4HLc to lock the Centre diff and drive to CT in front wheel drive?

I guess the diff oil may leak out, but worth looking at as an option?

Having read threads from the South African 4x4 community forum, South African Pajero Club and Australian Pajero Forum I’m posting this comment regarding the “thunk” coming from the rear diff and how it was solved in my case. I live in Plettenberg Bay and can’t speak highly enough of Dean Smyth, owner of DRS Motors who worked with me to resolve the problem.

I have a 2016 Gen 4 LWB with 113,000km on the clock and from about 108,000 noticed a “thunk” coming from somewhere in the rear when I was cruising at anywhere above ± 60kph and accelerated or deaccelerated – I could make the noise happen just by tapping the accelerator and as the kms increased above 108,000 it happened more and more often, at lower speeds and became louder.

I took the vehicle to the Mitsubishi Dealer in Somerset West and we popped it on a lift expecting to find worn bushes or something lose in the suspension – all was good. However, they did mention that they had seen the issue before, but couldn’t find the definite cause but it may be from natural wear in the prop shaft and drive chain. Nevertheless, they said the car was safe to drive.

On returning to Plett and after reading many blogs Dean carried out a detailed inspection of diff mountings, suspension bushes, wheel bearings, crown nuts etc etc but found nothing obviously damaged. However, he did notice that the “thunk” didn’t happen when first driving, but only once the car had warmed up. He then decided to replace the rear diff oil (this is normally done at the 120,000 km service). The manufacturers spec is for a Hypoid GL5 SAE 80W gear oil, but none was available. However, the Mitsubishi Dealer in George advised that they prefer the Hypoid SAE 80W-90 (in our case Liqui-Moly brand) as it has a wider temperature range and would still met the manufacturers spec.

It was like turning off a switch – the “thunk” immediately and completely disappeared and no amount of accelerating or deaccelerating at any speed can make it happen. We compared the old and new oil and apart from a slight darkening of the old oil there was no obvious difference - we can only assume that once the old oil heats up in the diff it loses some of its dampening properties.

So, before going the expensive route of diff rebuilds etc……try changing the diff oil.

One of the most common causes of rear-end noise under acceleration is worn or damaged differential bearings. These bearings can wear out over time, especially if the vehicle is used for heavy-duty applications, off-roading, or if the fluid hasn't been changed at the recommended intervals. When the Automotive bearings start to go bad, they can cause whining, humming, or grinding noises. The differential will need to be inspected, and if the bearings are found to be worn, they will need to be replaced. Bearings for the differential and axle shafts can be sourced from OEM suppliers or aftermarket brands like TBS or SKF.
