Clonking from OSR

[ruud2boy]

Howdy all
Looking for any advice. My '02 car has developed a bit of a clonking, coming from the right rear. I assumed it was a worn bush or something else in the suspension, but it's been in to 2 different garages now & neither of them can find it. 1st one said they couldn't find anything wrong. 2nd one changed the damper and droplink, but that hasn't cured it. I took it back to them for another look and he said he couldn't find anything else.
Went back to the 1st garage again earlier this week for the MOT doing (it passed!!!) and they said they'd noticed the noise - they said it's definitely not mechanical and suggested it might be bodywork??
What is there at the right rear that could be moving, but shouldn't be? I've had it up in the air at home and had a good shufty around, but can't see anything obvious.
It's not a regular noise, I tend to hear it when pulling away or accelerating.
Any advice gratefully received.

Brake pads rattling in the caliper? Mine did this on the rear and it turned out one of the spring clips had gone AWOL. Not sure I'd describe it as a clunking but it was a noticeable noise at low speeds.

The dust shield/plate behind the disc also rots and can flap about, but I expect that would be more of a tinny rattle.

Other than that, has anyone been working on that area of the car recently and might have missed a trim clip or screw?

Edit: long shot, but has something found it's way through the vent on the side and is moving about inside the panel?

Does the source of the noise sound the same if sitting in passenger seat?

[jvanzyl]

When does the sound occur?
When starting off on a drive? Changing direction (forward/reverse)? Cornering?

[ruud2boy]

Can't answer that, as it only occurs when the car's on the move and I'm the only one that drives it. I've had it 2yrs+ now and my missus refuses to go in it, NVM drive it.

It's usually when the car and by extension the rear suspension, is under load. So setting off or accelerating. That said, it does just happen randomly - but regularly. Every 20/30 secs or so, regardless of the condition of motion.

[Carolyn]

Floppy brake disk cover?  Loose brake pad?  Suspension bolts need torqueing up?

[jvanzyl]

Random chance your aerial is trying to go up or down and it's making the sound? So it can happen when idling at standstill?

It'd be worth a try getting someone else in it to confirm your thinking, or not.....

[Joesson]

Strange how the 2nd garage diagnosed and replaced a damper and a drop link and then had no idea where the noise was coming from!

I did hear a tail about a new , very expensive car that had a similar noise.
After much searching the source was traced to a spanner suspended in the rear driver door, with a note: So you found it at last you rich b*****d!

[Ardent]

I'm following this intently as I have similar only on the left side.

[Iain]

Strut top mount?

[ruud2boy]

Thanks for all the suggestions. I'll report back when my regular spanner guy has a look and no doubt identifies the problem straight away. He's been on holiday & then his missus has given birth to their first, so he's been out of action - hence cheating on him with the other garages.

[Chilli Girl]

He's certainly not been out of action - quite the opposite I would say     Hope you get it sorted.

Eventually coming back to this thread after my mechanic hero has assessed my 2. Quoted Ardent as he said he was having a similar problem.
As expected, after 2 other garages said they couldn't find it, my guy identified the problem & sent me a video showing / explaining it within 90mins of getting his hands on it. The clonking is evidently down to the inner CV joint and driveshaft at the OSR reaching the end of their life.
To quote my man 'The [CVJ] bearing cage is moving on the shaft. That'd indicate that the splines [presumably on the driveshaft] are worn. The bearings are practically rattling'.
So, I'm in need of a replacement driveshaft. Can anyone point me in the direction of a reliable supplier where I might be able to source one? I've contacted MR2Ben, JSpec & TCBParts - along w/ a Japanese website, JP-carparts. Any other suggestions gratefully received.

Also try "GT4-Play"?

You could also try Midlands and East Coast MR2, they are very helpful.

As I mentioned in 2017 when my 2 was on 63k mikes-the rear offside inner CV boot was leaking a creamy fluid that turned out to be the emulsified grease from the joint.
 I cleaned that and the other three boots and repacked the bearings with CV joint grease. At the time I asked if any other Members had noticed a leak from the joint. There were no takers.
Perhaps mine was not an isolated incident. I would think that the CV joint grease has a useful working life and perhaps that could be around 60k. If I had not cleaned the expired lubricant and replenished with fresh I wonder how long before the joint wore out?
Just maybe the CV joints need periodic cleaning and refreshment of lubricant to keep them running.

NB.
I do recall an Austin 1800 , a Big Mini , in period, with a collapsed offside front with the CV joint clearly disengaged. Much development on CV joints since then , but there demise can be dramatic.

Sounds like absolutely solid advice. The video clip Jack sent me has the very same creamy, off-white susbtance oozing from the joint. In fact, when I can track down a replacement driveshaft, I'll ask him to repack the boots on the other side as well. He seemed pleasantly surprised that the boots can just be peeled back without actually removing the shafts.

The first set of after market replacement clips that I bought had inward facing barbs that I felt would damage the rubber boots.I discarded those and bought some clips with outward facing barbs from HCL Fasteners Ltd. T: 01761 417714.
I bought: OEC-23 W4 Oetiker 304 SS Adjustable Ear Clamp-W  x 2
          OEC-28 W4 Oetiker 304 SS Adjustable Ear Clamp-W  x 4
          OEC-83 W4 Oetiker 304 SS Adjustable Ear Clamp-W  x 2
          OEC-89 W4 Oetiker 304 SS Adjustable Ear Clamp-W. x 4
I was unsure of the sizing and and my competence at fitting them so bought different sizes and spares, I can't recall which fitted.
Either the unused clips or those that I used came with a fitting tool, a special plier type tool. It was of little/ no use. Fortunately my neighbour had the correct tool and the loan of that meant fitting was relatively straight forward.
A picture is worth most of those words above but today the imgbb won't work for me.

@Joesson
Thanks for the above, but I'll leave that to the spanner guru. More concerned ATM w/ finding a replacement driveshaft. Hasn't really occurred to me before this that some parts wouldn't be available any more.
Has anyone ever heard of J&R Trading? Website looks good & suitable part available, but the online reviews are peff.

[Ardent]

Never hear of them.

No idea if I'm talking nonsense or not, but thoughts that popped into my head. Is there a difference between PFL and FL drive shafts, 5 or 6 speed boxes.

If you spank your vin number into here https://www.amayama.com/en you should be able to pin down the part number.

Apparently so. MR2Ben asked what 'box it had and TCBtoyotaparts have asked whether it's PFL or not.
The Japanese place I contacted have sent me the exploded parts diagram for both sides - just need to figure out which part ref covers the whole shebang, rather than just the individual bits

Might help. That based on uk 6spd
