poly or rubber bushes?

my dad has got it into his head that he will supply a complete set of poly bushes and i fit them. However, the bushes are all good with no play in them.
should i do as i am told and replace the lot or dig my heels in and save money and time?

Well if you're dad's buying, I'd go for poly bushes, its only time on you're part then. I think you will benefit greatly from the upgrade, so go for it. Only go for good bushes, and shop around, as prices vary as does quality.

If you are fitting poly bushes smear them with grease to stop them squeaking

Poly bushes are the best upgrade you can do for the money, they are durable and you will notice that the car is far nicer to drive, steering is sharper etc. you will think you are driving a little sports car instead! In my opinion they are a huge improvement I fitted them to my current vehicle and also to my van 10 yrs ago. (Slightly different set of bushes for vans as rear spring mountings are a bit different)
Even just replacing the tie rod bushes with poly seems to make a huge difference, go for it.

If your current bushes are good you could always replace them with poly a bit at a time i.e do the front first and tackle the rear when you feel like it. I got the rear spring pads in poly too from esm.

A word of warning on poly's though, the colours do state a different density. Now see if I get this right.... yellow is the softest then followed by purple, red is harder again but the hardest of all is the black. Power flex can supply black ones but takes two weeks to manufacture them. They are p56 or something like that.
Now the other thing is a thought on whether you need worry about the grading on a morris at all really, as I say yellow is the softest it is still bloody hard. Its more the lifespan. A moggy being pretty light probably won't eat through them, where as a bmw E34 thrust arms will turn them into playdoh in hours due to the weight of the vehicle. I fitted Blacks p(whatever the number is) all round on a spitfire I restored for a friend as it was his intention to drive it like the sports car it was meant to be, and then some.
So in conclusion, if you intend on giving your moggy a hard time then look up the scale of harder polys but if standard and normal driving then sit with yellow purple. Im sure jonathan can advise nicely on this issue, and I agree with him, there are some too good to be true sellers on ebay, so beware. Power flex can give you a number of a reputible seller, but personally for the moggy I'd stick with the experienced moggy handlers and call Jonathan.

We've always fitted red. They last. Who wants to spend their life refitting the suspension.

This should explain the shore hardness for the Minor bushes.
The black bushes are no longer available

Guide to Hardness Selection

It has become necessary to dispel many myths & misconceptions on application of hardness caused by imitation.

SuperFlex grades are all pre determined in hardness suitable for road to fast road use. As a customer, you do not have to choose the hardness, unless an option on our listings.

On some cars all four production hardness are applied in various positions around the car, depending on the load in that location – as tested and pre determined by us.

Colours of SuperFlex bushes do not identify hardness, with the exception of 95 shore which is only produced in red.

To simply blanket a car with one hardness and call it: comfort, dynamic, performance, race, road or touring displays compromise or limited production capability and doesn’t work.
See selection chart below - based on nearly 30 years PU manufacturing experience:

Guide to Hardness Selection
70 Shore Typically subframe mountings where low NVH is a priority and situations where compliance is desirable
80 Shore Typically wishbone, radius rod, non coil over shock eye bushes
90 Shore Typically leaf spring eyes or more heavily loaded wishbones & radius arms, trunnion bushes where replacing rubber
95 Shore Typically intensely loaded coil over shock bushes, trunnion bushes where replacing nylon – red only

For certain motor sport applications we can make bushes typically in firmer grades to special order. The lead time for this service is 4 weeks and is subject to a minimum order of 100 pu pieces of any one part number.

Guys
Just bought a set of polybushes from another reputable supplier Special offer (0FF106) and they are all green! On the website they are mostly red. Any advice or comment

Is your dad going to pay labour charges?
If not, I'd wait till the rubber ones wear out then replace both sides at once.

Ahh, Bull Motif ones then. Nothing wrong with them,(apart from the horrid colour), and I'm sure that they conform to the shore ratings that I have posted ?, but do they come with a lube and carry a 3 year warranty ?.

Unfortunately not - still learning from my mistakes - only been a Minor owner for a month might try another well known supplier next time jonathon!
Thanks

Odd, when I spoke to ah powerflex not superflex, just clicked. Powerflex do thier hardest in black and is a two to four week wait. Had to do my e34 in them as the yellows couldn't put up with the load. Interestingly when I spoke to them they said the same thing, "our yellows don't last on the front so you need blacks".
