If I was considering freshening up the bushes throughout the car are polybush a reasonable upgrade and which ones are worth doing first?
Also which ones are possible DIY and which need presses etc?
Thanks in advance!
No definitely not poly. Standard all the way
Any particular reason Sparks? I know they make a Biiiig difference when installed on a MK4 Spitfire diff, but that’s a different kettle of fish!
The original bushes on the MX5 were engineered for the car rather than picked from a rubber bush manufacturers cataloge and suit thr car.
Many people find poly bushes too hard and noisey on the MX5.
Other people cannot stop themselves fitting polybushes.
There are MX5 specialists who advise fitting poly bushes and others who do not.
The other issue like the original poster has is they say let’s “freshening up the bushes throughout the car”.
Many people who have done that without checking the original bushes find that the differeance they find in the car is not worth the effort.
Do not fix anything that is not broken, only change bushes that you can prove are faulty.
Bushes are around £350 or so to do a full set, maybe more and take a lot of time to do and may end up damaging the wishbones getting them out and plenty of the bolts will be seized.
As advised only fix what you can prove is broken or for instance when the wishbones are already past there best.
“Standard” bushes are nail hard and incredibly durable anyway.
I’ve just replaced some 26 years old ones…and some were actually OK still.
Hiroshima got them right. Stick to OEM in my opinion.
They don’t promote NVH or need squirted with WD40 every other month.
Drumtochty has put it in a nutshell.
If it aint broke dont fix it.
I think I did as well.
We’ve just bought an NA and I find the ride very ‘jolty’ and are wondering whether it may be a suspension bush issue, or whether I am expecting too much. On smooth tarmac there isn’t a problem but on tired old surfaces, ie, 90% of Ireland’s secondary and back roads, every patch and pothole rattles the car throughout.
I’ve owned Minis and series one Land Rovers in the past but this is the most agricultural ride I’ve experienced in a car. It handles well and there is no bounce in the shocks, so is it normal or should I be looking for anything in particular?
Turns out a couple of shocks are blown after all, so its new units and springs all round.
I have a 2016 1.5 ND.
I am a firm believer that “If it ain’t broken don’t fix it” but have been advised that my rear suspension may need attention in the coming months prior to MOT.
I have 3 questions:-
- I think it is possible to replace the rear hub carrier rubber bushes with poly bushes. Am I right?
- I appreciate there are NVH, and through time lubrication issues with poly bushes, so would like to know if it is possible to replace rear hub carrier rubber bushes?
- Or does the rear hub carrier need to be replaced?
