Thread: Problem with front radius arm to axle Superpro bushes

Unless original is not available or stupidly priced ( not the case here )
I cant see the attraction to eurothane "bushes" . first up they are not bushes like original black rubber where the inner and outer sleeves are bonded (vulcanised) together and the rubber itself twists. They are more like a bearing and the inner sleeve grinds away at the eurothane, so they will not last as long as the original (noticeably true on shackles , especially where dirt is involved). Also being stiffer , (advertised as being some sort of advantage ) in the the front axle radius arms this inhibits full compression and drop out on opposite sides of the axle as the arms need to be able to roll in the mounting locations for this to happen and on the rear bush at the chassis it also wants to be supple enough to let the arms drop down (eurothane will hold them up to some degree).
They also give a harsher ride. They do look good on hot-rods as you can colour match with your paint scheme.
The only plus side is they are often easier to fit as some part numbers do away with the outer sleeve so no need to press in, and once fitted the suspension doesn't need to be set to ride height before tightening because the bush is free to rotate ( a big plus for people who don't now what they are doing ).This procedure is not relevant to the front axle in question.

God I get sick of repeating this but Super Pro bushes are of the same durometer or softer than OE rubber, only their competition/extreme range are harder than stock.

They are also of a superior (IMO) design in most spots of a Rover, particularly the chassis to lower trailing arm bush and radius arm to chassis bush and none of their bushes are patterned after the OE style bush, unlike most urethane bushes which are often direct copies of the OE bush.

They tend to last significantly longer than OE rubber, most of us that use the Super Pro bushes have doubled or tripled the life of the bushes by using SP's versions, as well as generally increasing articulation and retaining stock ride characteristics.
FWIW the latest OE rubber bushes don't have the best reputation for life, and I'd be loath to recommend any other brand of urethane bush.

Put a rubber bush on one of your foreheads and a eurothane on the other then slap them both like some sort of an immature Bart Simpson and see which one hurts the most.

Where do you get your info from regarding hardness ?
I get mine from many years of experience and I am yet to see any brands softer than rubber. Fitted a set of sway bar links ( superpro ) last week , hard as , needed to compress the bushes first before getting the nut back on and then you can barley move the link sideways in relation to the sway bay when tightened !

If thats how you perfrom a test of these bushes with all your years of experience, then Im a little concerned with any other advice you might give and how many foreheads do you have? Not from Tassie are you?

you also said "They also give a harsher ride. They do look good on hot-rods as you can colour match with your paint scheme.

right there you pretty much lose credability. You can not color match Super Pro bushes (which this thread is specificly about) They give pretty much the same ride as OEM, but not too many people are pulling out brand new OEM bushes to compare to brand new Super Pro, so the difference is lost in ware. And the radius arm bushes at axle end do not have a outer sleeve so that exactly applies to SG1's axle in question....

I would not be suprised if the guys at Super Pro designed the sway bar bush to be stiffer. You do realise they have the ability to change hardness etc at the design phase right?

If you are bunching all urethane type bushes in the same basket, I could only assume you think all brands of ruber bushes are equal also....

NO "Uninformed" I designed that test for your mentality.
I thought this thread was about a clunk after fitting non gen bushes that happened to be Superpro. He never said he had a clunk with originals
If you had any comprehension skills you would see that I don't discriminate against superpro in fact I mostly refer to eurothane in general which you can choose many colours if you dare stray from the almighty Superpro brand that some of you seem to have shares in or make money through sales .I also sell a mostly superpro as my main supplier pushes it BUT I always try for rubber first and will continue to do so. A forum is always going to be about opinions and I am still yet to see where it states that superpro is softer than rubber.

so all shock absorbers are the same? All ARBs the same, all tyres the same etc.. Its not rocket science, it has been proven already on LR products by many here and not.

Since you bring up comprehension skills and have many years experience, do you think that possibly the act of changing the bushes themselves could be the issue, not the brand or type? i.e. the fact that bolts have been undone, components removed etc? Yet you seemed to jump straight on the "urethante is bad" wagon.

UNINFORMED.
Obviously YOU didn't read my FIRST sentence.

" The inside of the brackets are probably worn a fair bit and as was mentioned renew the bolts also. When I did mine I had to retighten (very tight) a few times but it finally took up. "

I then went on to give MY own opinion on eurothane bushes in general, ( sorry about that ) based on my experience "professional " as I make my living out of it.
It is clear that this differs from your opinion, SO WHAT.
Did I mention my FIRST sentence , or cant you see past the eurothane spiel I gave , and that you took that personally as a dig at Superpro.
Did I also mention that I don't like any eurothane regardless of colour or nationality.
Still interested to see where it is stated that superpro is softer.
Talking about all the same, I have never been asked with eurothane type bushes would I like soft medium or hard and never asked if I would like fries with that either.
