I would appreciate any help please.
I have an ND, nearside knocking and a Mazda dealer quoted £919.60 to replace complete hub on NSR.
Mazda will not help, saying incomplete Mazda Service History, suggesting a sealed non replaceable joint needs servicing?
Can anyone on this forum recommend a proven aftermarket solution and especially, a trusted fitter who has done the job before?
Preferably sited in the Herts/Bucks/Beds area.
Regards
Bunch of utter shysters.
Incomplete service book? As usual, the size 2 font in subsection whatever on page 104 will cover Mazda UK.
Never the less how do you “service” a bl%%y sealed non replaceable (sealed for life?) suspension unit and what’s THAT got to do with the price of fresh haddock as a knock out point?
There’s bound to be scrapped ND’s about… but what are the G’tees?
I’ve read a while back it’s not rocket science changing it out but perhaps people like Paul Roddison could advise properly.
It seems there is a variety of rebushing solutions.

This Rear Hub, MX5 Mk4 & RF (mx5parts.co.uk) is the Mazda complete unit and these Polybush Rear Hub Upper & Lower Lateral Arm Bushes, MX5 Mk4 & RF (mx5parts.co.uk) are the bushes for both sides.
If you have the facilities to remove the whole hub yourself then may be MX5 Racing - Roddisons Motorsport (mx5-racing.co.uk) could help.
This Manual pages - MX5 Manual | Mazda MX5 (Mk4) 2015+
covers the removal process.

Andy Leslie can supply new bearings (they are not bushes) for the hubs and you can contact him on Facebook

Can anyone advise me how to contact Andy Leslie, rather than using Facebook.
Many thanks.
Regards.
I’ll send you his e-mail by PM.

The photo showing the failed polybush could be just a poorly fitted bush i.e. bolts torqued up with suspension at full droop, of course it could be the fault of the bush, but I can remember years ago when the Mk3/Mk4 Cortina’s were current and I worked for a motor factors at the time selling the replacement void bush that didn’t have the void in the bush, and garages would constantly fit them in the full droop position and they would fail as would the genuine Ford part if fitted this way, on questioning the “mechanic” he would not know about putting weight on the suspension before torquing up. I also find it strange that Roddisons, who according to MX5 Parts helped develop the bush, would put his reputation on the line. I don’t know and have never used Roddison’s so I’m not blowing smoke up his a**e, but he has a very good name in the MX5 world. It would be nice to know what testing he did on the bush, did he fit them on his race car, for instance?

That’s very good to know.
Be aware that the ‘bushes’ are in fact spherical bearings and the reason they fail is that the rubber seals allow dirt and water get into the bearing causing premature wear (there is a TSB on it). Andy Leslie manufactures new bearings (fromTimken) to replicate the exact movement of the original.
We have fitted literally hundreds of poly type bushes with zero issues
Just today I’ve fitted a set to a P+P member.
So without evidence please do not discuss them

Hi BlueAgave, yes I do know they are spherical bearings, and Ford has used them in the past (without any problems). I was just pointing out that the photo of the failed bush could have been a fitting problem and might not have anything to do with replacing a spherical bearing with a bush.
Sorry guys
My post about should have said
Do not diss them……
We have tested them rigorously with no issues whatsoever

I believe the reason the original bearings fail is that the seals fail allowing the lubrication to escape and moisture to get in. No way back from that.
Rodders is probably right that the reason for failure of the Polybush which has been pictured is incorrect fitting.
However my personal preference would be an upgraded bearing over a bush. If a bush of any description would provide the same performance as a bearing why would Mazda use a more expensive bearing in the first place.
I’ve had one hub on my car replaced by Mazda with a contribution so worked out cheaper than either option.
If any of the four bearings needed replacing again I would buy the set of four from Andy Leslie.
I would want them fitted properly though and there’s no doubt I would go to Rodders for that. Maybe he might grumble a bit about me not going for Polybushes but I gather that a supply of biscuits always clears the air on that front.
