ebay as normal..   you need to make sure the aux shaft is lined up correctly or the extra stress will make them fail earlier.
Normally around 2+ years is what i have had per set.

gonna use jap auto parts this time. last ones came from the estima club or something like that lasted 6 months. dont think there still on ebay then again could just trade under a different name.
jap autos are doing toyota ones for �125. missed it last year they had them on a half price sale as usual i didnt have a pot to p in at the time.

These are the ones I bought from this time as autojap have hiked the price and bellocat have too.

auxillary shaft couplings estima 91-99

Exactly same as other sellers for quality and bolts.. use the self locking nyloc nuts.
So should last another 2+ years, fingers crossed.

Same seller and same picture on listing as the ones I bought
Part numbers look different, but will be difficult to tell if same parts or not without having a set of each listing side by side.
But the 3 year guarantee sounds good  Undecided

ok sads still rattle and i think it was down to human error.
I see from  tutorial that you had to mark the sads up with the aux shaft or something, i didn,t.
i noticed from memory there is a small like metal plate half way down on the prop shaft, is this a marking or how would i know were to line up so its balanced.
i,m due to buy another coupling but don,t won,t it to wear out quickly again. happy days again lol

OK when the SADS go, what sort of noise will i be hearing. If i got to get under the Mystery Machine to do a couple of things i may as well look at doing these as well!

knocking noise from front of car, if you let it tick over, then switch on lights and heater, should notice it more, then switch off again

the thing that strikes me is there solid rubber.
polyurethane supposed to be really strong would have thought they would last forever. you would need a press to get the old ones out of the disc and them ones in.
id say they would last longer than the car itself.

a member from another site has just fitted sads from
http://polyflex.com.au/3-Bolt.php
said they where a little smaller and caused a lot of vibration
this ia a quote of what bryanj done (stolen i hope you dont mind)
"I have improved the Sads vibration quite a lot. Not as good as with the old ones but close.

Firstlly I pushed the rear mounting bolt on the horseshoe right forward and loosened the two front mounting bolts and allowed them to find their own home.

Then out with the dial gauge and set it up near the large part of the shaft towards the front. Turned the shaft and found the high spot. This was eight points on the gauge. Not sure of the measurement size it's to long since I used it.(25 years I think plus old eyes now)

Fitted two old turbo hose clamps that were stripped in one place just back from the small part on the front of the shaft with the screws opposite the high spot. Just happened to be inline with an original weight near the engine end.

Vibration area reduced to 1000rpm to 1100 rpm area. Previous was up to 1600rpm and the fan used to shake about like mad. Not so mad now and driver getting better.

Also removed the Toyota washers from the front Sad that I was fastidious in getting to 90deg on the three fitted and replaced all with thick falt washers.

These are not needed on the Poly sads and were only used due to lack of thick washers.

This made it just a little bit smoother. Then I did 100kms run at highway speeds above 100kph. After 50 kms more improvement noticed.

I think the poly sads are in need of a good thrashing and some heat. A good thrashing it got.The van was definately smoother on return home and I can only hope it will contine. Cold start in morning will be interesting."
so theres a lot to account for when replacing the sads, i think it also comes down to if the new couplings dont weigh the same that will also cause vibration.
I hope this helps

I don't think there is an actual line to fit the shaft to balance by. I know the couple I've been involved with, we just fitted the new couplings, and refitted the shaft without any particular reference to a line. As the shafts are balanced during manufacture they can be put on any car without having to dynamically balance on the car afterwards.

The weight difference doesn't really have a lot to do with it more that the couplings are properly made and their weight is even around the circumference. Same thing with car tyres, if you had a heavy duty set or a light set fitted, its all down to imbalance in the tyre itself hence the need for balance weights.

Making sure the shaft is fitted correctly with washers in the right places is the best way to minimise vibration. If you need to, adjust run out by rotating the shaft to another position then reconnecting, should minimise any offset rotation of the shaft. As for a good thrashing, any new moving component should bed in before you will get the best result from it.

Doesn't work like that. The shaft would have to be made level before initial removal, not the car as there will be some difference between the car and the shaft attitude. Also where would you take the level from on the car? Aircraft have rigging points that you jack to level to a defined spot. Can't do it on a car because there are so many variables due to flexible mountings, wear, any damage to the drivetrain as a whole as well as maybe the chassis on the car.

Hi I posted in the wrong place about my polyflex sads. Under the pump o ring etc. Suffering from Estima psychosis I think. Sorry about that.

Will get better at it eventually. I don't think it is the size difference as it is very slight in diameter and the weight is similar by feel.

They are just so hard and not forgiving. I will ring Brisbane today and ask some questions from a place called Driveline Services who fit them. A lot more Estimas in Queensland than here in South Australia.

I think they feel a little worse when cold but still a big improvement with my rough balancing etc.

Not to much shaking this morning but worse with a/c on.

it was more of joke really. i didn't think for a second that a spirit level would work.
If you see a red Estima pull out side your house Gary don't worry just me coming to get you to do my sads looks like you know what your talking about.

You could say I've a reasonable amount of experience with driveshafts. Just not usually on cars as they are pretty limited in what you can do with them and their connectors.  Wink

Yes, I can see how turning it could change the high and low position, but wouldn't this just move it to another location?

I still feel that the couplings are just hard and unforgiving.

Still when you consider the rear tailshaft of similar length has solid uni joints. This is also the case for 4x4 vehicles and these don't shake.

The balancer that I spoke to said similar and avoids these front shafts. He also said that most tail shafts run a bit out of true and hence the need to balance.

I will just run it for a while now and hopefully it will improve or I will get sick of it and get the original ones.

I rang a company called Driveline Services in Queensland and told them about my issues.

They advised me that they use these couplings exclusively on the Tarago (wide body) that is in numbers here and also on the lesser numbers of Estimas.

Never had a complaint or noticed any of the problems like mine. I was told that rotating the shaft won't fix it as they don't worry about the old position when fitting.

They suggested balancing the shaft as I have improved it with my bush balance technique or just go back to the Toyota couplings.

 I have had enough at the moment and have to start a new job next week and study at uni towards a Masters. So I will give it some use. The vibration is only now over about 100 rpm and only noticeable when a/c on at the lights.

well spent the day under the bus today replacing my sads, managed to do it without bothering belts took the one off by the engine first then pulled it to drop the front one slipped the new front one in did the bolts up. had to losen the bottom bolt of the horse shoe got My mat to pull the front reassembly so i could pop the sad carrier and aux shaft into position did the bolts up. had to fight the horse shoe to get it back in to position started up and no more noise.
 Yippy I did it at last oil change done as well sweet dude.
3 hours It took me.

well done tony, still haven,t touched mine yet, althou the exhaust is sweet now.
did have a chance of wing, headlight and glow plugs for �50, collect, but weather was bad here and couldn,t collect. Phoned the guy today and he scrapped the car, worth more apparently, he takes things off like diesel pump etc.
So back to the drawing board again. lol

that's a shame Jon. I think the main difference with the sads was i used a better quality one this time. the rubber is stronger than that of the cheaper ones. Which i think is more the reason i had no hassle with rattling noises after.
You get what you pay for i suppose. no more cheap buys for me.

family gone down too Leeds i got to stay here and work. Flying down to London on Monday to catch up with them.
piece and quiet.
Spent my day running network cables Upstairs and putting sockets in. tried the old wireless route got fed up with the kids complaining that there internet gone.
