Hey guys,


Great forum! I'm hoping you can help me though!!


I've trawled the web and I'm still at a loss!!


I have a 91 KZN130, with a 2" body lift 2" monroe suspension lift and sitting on 35x12.5 tyres!


I took it offroading over the weekend and I've developed some issues


I have 2 problems they may be connected, they may not be!!


The front diff is leaking on the drivers side (JDM car), on the left as you look a the car front on. I assume this is just the seal so have ordered a new one.


The second is the more worrying issue!!!


I had a nasty knock/ rattle when going over anything other than perfectly smooth roads. I searched and I got the impression it may be the ARB or droplinks so I removed this and retested.


This has made the problem worse! It's a nasty rattle/ knock that can be felt in the footwell and in the steering wheel.


It litterally feels like something is broken/ loose and rattling about. It happens when going over anything less than perfectly flat tarmac and seems to be less apparent when conering.


I haven't tried it in 4wd due to the diff leaking a lot! but it's definatley doing in 2wd.


On looking and bouncing we have seen that the bush at the top of the shock is moving onnthe drivers side up and down as we bounce but it doesn't on the the other side?


Any ideas on where to start looking??

Gosh, it could be so many things.

Or it could be that. :)

Snug up that bolt and bushing, see if it still does it. Other places to check if that's not it - a-arm bushings, sway bar links, ball joints.
 
Thanks for the input.

It can't be the sway bar links as I thought it could be this and removed the swat bar (Anti roll bar), and this made the noise, shaking far worse.

It's the bush on top of the shock, that we could see moving, I will try and tighten that up this evening.
 
I think I've located the noise!

The leak and the noise are connected.

If I grab hold and shake the driveshaft it moves and the noise is similar, the the side without the intermediate shaft, shaft from diff to hub.

Now is this going to be expensive or cheap??

Try that again, I think you a word there.

Your pic looks like a picture of the halfshaft and CV joint, are you leaking where the halfshaft joints the differential? Or are you leaking at the pinion on the rear of the diff where the driveshaft attaches?
 
Better pic



I can move it up and down (towards the bonnet) but not side to side front to back.

Could this cause the noise/ thump in 2wd??
 
Just been out and cautiously checked and it makes the same noise going over anything less than dead smooth in 2wd and 4wd
 
do you have the ability to lift the entire front end off the ground and put it on jack stands... if so get all of the weight off the front suspension and check the bearing play in your front hubs (usually do this by pulling in and out on the wheel while on the ground as well as your steering components upper ball joints will make some strange noises when there worn out ...

lock 4X4 in & drive in a tight circle if the CV is shot youll hear it!
could be shock, bushing, or bolt.
could be ball joint.
Could be an A arm busing.
could be a wheel bearing.

Here if I have an issue I cant find (or dont have the time to mess with finding it) I take it to the tire shop (Big-O) & say I think Ineed an alignment & ask if they will check the componnts before I have it done. They do it for free & tell me what need to fix (of corse they want me to have it done there, but i say I need to figure out my finances first. then I go home & fix it.)
 
I've had worn out shocks make some awful rattling noises in my runner. The housing separated from the shaft.
 
Well it's now in my friends workshop.

It's not looking like it's a bush.

It's unlikely to be the diff as in 4wd (ON GRAVEL) turning in figures of 8's doesn't give any diff like noise.

He's thinking maybe the front driveshaft (Axle to you guys), Shock, or something else! He didn't have time to look yesterday properly.

I'll update when I know more!
 
Well it wasn't the shocks!!

Best way to describe the noise is metal on metal banging. Like it would if something was loose or broken and hitting into something else. It's not a quiet noise and can be felt in the footwell and steering.

It got a lot worse when we removed the arb!!

It happens going straight and turning, in 2wd and 4wd.

It happens all the time really, only on glass smooth roads does it not do it.

As the diff was leaking and there is movement on the drive shaft I've ordered a used diff to see if that cures it.

After that I guess it can only be a bush.
