Noises 2

Post by paj94 »

I’ve got Pajero 1994 SWB 3L petrol motor with man gear box.

I have a problem getting it into gear but strangely it is not always.
When you start the car or changing the gear, you cut the clutch and slowly meet them to transfer the traction.
The moment my clutch meets, I hear very loud creaking / vibrating noise while driving.
It goes away when the clutch is completely connected.
I have no slipping on the clutch on all the gears.

Is it could be a simply adjustment or do I need something major?

Any advice is appreciated.

I'd get it checked.... my Nissan was doing that, about 2 weeks later the gearbox shat itself :( The front countershaft bearing disintegrated.

HI, there is no adjustment for Pajero clutches, I have just replaced mine at 80 000km's.

Its not something really simple like the pedal squeaking is it? Get someone to work the clutch for you and get underneath - see where the noise is coming from. :D

noises 2

Post by cruiser_beast »

I just had mine at the mechanics today getting checked for my noises, he reckons it could be krap in the bearings maybe in the clutch, that will casue a squek, and reckons it could be the bearing sticking sometimes, or whatever, but he said he had a mate who drove round for 9 months or something with pretty shot bearings (making terrible noises he described)in the clutch system with no damage.

He reckoned that the engine i had wouldnt rev high enough for the thing to go nuts and disintegrate and take out a lot of the clutch system if it went, and didnt think mine was near going, but your problem sounds a bit differewnt to mine, mine was just a mild squek, and maybe a chatter sometimes.

Sweet, would pay to just drop into a mechanic. If your near the north shore, go to "4wd services" on target road. knows his stuff.

Thanks All,
I have a garage appointment on Tuesday.
I will mention this to the man.

I have got any squeaking but it is terribly loud one.
It could be a clutch or may be a gearbox, but it mostly happens when the clutch is half met. (Intentionally slip the clutch to avoid jumping the car when change the shift…).

See what’s the garage find out for me.

It looks like one of the baring start seizing.
I smell something is burning when the half clutch position was little longer. This was never happens to other SWB that I had before.

Do few more isolation test befor booking the actual job...
The clutch itself does not slipping, when only the drive is on board....

I'm totally confused now. :?
It could be anything...
Clutch, wheel baring or may be one of the pulley was faulty....

NJV6,

When you put new clutch on yours (at 80,000k), have you noticed obvious slip? - Like the rev went high but no movement or acceleration....

I haven't had alot to do with pajero gearboxes but I have repaired several mitsi L200 and L300 gearboxes and the noise you describe sounds like the front main input shaft bearing which is common for these boxes, the noise is the input shaft shuddering just as the clutch engages.I dont know if this problem is common on pajero boxes but a call to a reputable gearbox specialist would probably confirm this.,hope this proves helpful.

HI, yea I certainly did notice it slipping. It hadn't done it at all, then pulling from an intersection full throttle 3rd gear, ( i love the sound of the V6 with a big pipe.... :D ), I almost didn't think anything of it cos I was just in the proces of changing gears then next time I was off roading, attempting a steep climb in 3rd low away the revs went, thought I was skidding but the smell let that away. From then on the pedal went spongy very quickly, was wierd thou that other times I could use full throttle in 4th and 5th and it would hold.

Basically the mechanic told me it was buggered, and of course because it was wear and tear the warranty company wouldn't pay, silly thing is, if it had been covered in oil from a leek they would have!

Perhaps I should have been wary when I bought it because the pedal uptake was well out. And yes there was a reasonable bill to go with it, at least I have a good clutch. I think from what I can make out they are a weakish point. There is another 3.5l manual one near me and its clutch was done at 120000k, he said it was fine then one day it simply wouldn't go into gear.

Sounds like it's best you get yours looked at, even take it to more than one garage if you like, get a general opinion.
Cheers,Glen

Thanks all.

Weird things are it’s not always happen.
I haven’t got any problem in last couple of days.
Last time I had this particular problem is when I had a passenger with me and try to backing up my drive way. It was a slope going up…

I tested each gear with handbrake full on for slipping but all passed.
(I got stole on each gear.).
So, I think the clutch itself is ok but may be one of the bearing.

I was quoted the labour about $437.50 and clutch kit for $270.00.
If the flywheel is required to match it will be extra $30.00 and GST over them.

Also, if the bearing was seized and clutch cover was broken, it will be covered by warranty…

I will check around some more opinions.

Thanks again!
It’s such a good forum! :)

PS.
If it needs to remove gearbox and replace clutch assembly, I may ask to put new clutch kit regardless, because the labour cost is so large portion, so I do not want to do this again so soon when I get really slippery clutch.

Yea, the labour for mine was $300 but the clutch kit itslef was $1100 :shock: :shock: :shock:

It was some fancy thing, I guess the 3.5's had a different one, I still might enquire as to why it was so much. The mechanic told me about 700 for the job so you can imagine my surprise and a few phone calls when I got the bill.

Gosh, that is a surprise. I will double cheek the quote before asking… :wink:
I think 3.5 has heavy duty version of clutch (later than 3.0) as a standard.
It may count to the price.

Yesterday, I get into the under body and removing some stones and bits.
Then I found small metal scalping at the end of rear drive shaft (at the end joint), :shock:
As it has lowered suspension before, it may be not properly adjusted and it caused the scalping noise… If it was it no cost to the job, but I will bring the Pajero to garage this Friday to confirm that and ask some cheeking around there.

I do not have this noise since this last Sunday. It’s gone by self. :?:

It was real mystery now.
No noise no faults, it’s totally gone.

Clutch checked by several test drive and nothing was wrong.
I told and show that small metal scraping piece to mechanic, so they took off rear drive shaft and check then reassemble.

I was told nothing was wrong.
So we endup agreed that it could be a small stone clashing at joint or some sort. (And I leant that check all the small stones picked up first.) :oops:

However, it was confirmed as good condition. This is the thing.
I’m ready to explorer my favourite places again. :D


No, I didn’t replace clutch kit this time. :wink:

Belts in the engine bay is usually squeeling or screeching noises... it would be worth while getting a hand in there and see how much slack is in them, on the Prado its supposed to be about 10mm....

Thanks Bill,

The play in the belt is Ok and theya re quite goo dcondition.
I fond some post in other place taht som euser sayingto move alternator slightly fwarede to solve noise on the belts and fun. Apperently it was common issue for Mitsui, but I do not think that was the case.

I'm thnking thats oneof those bearings somewhere or input grear that someone mentioned in this thread.

I complained to the dealer about this and they are going to arrange diag nose for free of charge. I will see what's comback from them.

It's back from mitsui dealer and they replace the fun belt and pulley.
Most of small noises are gone and apparently they did quite good job to eliminate noises.
But the one driving me mad is still there, but just get less frequently.

The service manager at dealer suggests me to test for week end and or may be whole next week.
If the noise is there, he will test them again.

It’s all no charge! :o What a nice service… :D
