either use a second solid knuckle or the original rubber ones with a V8 or they will melt

On the packet they state that the poly coulpling must not be used close the hot exhausts and a heat shield are recomended, when I fitted mine I used the original LX coulpling it's not rubber and my extractors only clear the coulpling by about 10mm. Either way you must run the original safety plate so if the rag joint fails you won't loose your steering.

It would be worth seeing if you can source some reinforced rubber to make a replacement poly section. Possibly an old conveyor belt.

Maybe this.

Using a second uni joint is also an option as others have mentioned. You may however notice a bit more vibration in the steering wheel. The only function of the rag coupler is to isolate the steering from the rack to reduce vibration. I am sure I read somewhere in the NCOP that you are required to have a vibration damper in the steering.

i dont know if u can get an original style coupling.if u find one,can u let us know please

Hi ass308,

Take a look here.

Ive had a Nolathane(red urathane) coupling on my steering for 15 years and its V8 with extractors but I have a UC front end which has the heat shield cover & bracket for protection. Its hasnt failed or come loose in that time.

I'm becoming very sceptical about Noltecs(blue urathane) products lately and there longevity. This is my personal opinion.

I didnt realize the superpro where blue as well. My mistake.
I only say that because the last fews weeks Ive helped change bushes on a couple of my mates cars which had the blue bushes and they where chewed out bad. They only lasted half as long as my red nolathane ones and they wherent near any heat sources.
As I said, I'm becoming sceptical.

Check on ebay, there are N.O.S. steering couplings on there all the time. The price range is $120-160.

A few US cars share the same rubber disc (different body coupling)

If someone can get me the dimensions of the rubber... diameter , thickness , bolt spacing... I'll look around

I saw a few different styles and sizes in an auto parts store the other day in LA

10mm thick, 70mm OD, 50mm centres between holes

you can change the rubber joint for a second uni joint, it does fit as i used to use it. no hassles with exhaust heat then and steering is a little more direct. just suggestion for you.

[fatslr]

Are you useing the second uni joint ? Ozy
I would have thought every V8 torana would have converted to this setup if it is a good thing as i have ended up running exhaust wrap on my extractors to try and protect steering coupling from heat of exhaust .

[ozyozyozy]

yeah i was using 2 uni joints, only reason it is different know is changed to power steering. never had a prob with 2 uni`s, was in the car for years, used on the track alot. from memory you may have to shorten the middle shaft a fraction with a file, it was a few years ago when i put the 2 uni`s in.

[LXCHEV]

I have a lot of mates who have also replaced the coupling with a 2nd uni joint (minor mods required to the shaft to do it, as mentioned above). They reckon it's superior, no more worries about breaking/melting the couplings (especially the new style ones), and they also report back better/more direct road feel.

I'm pretty sure the only reason the factory would have fitted the couplings, is for vibration dampening - the sort of thing you expect from mass-produced family friendly cars etc... but for car enthusiasts, especially with hotted up performance ones, I reckon the 2nd uni is the go! I have been meaning to change my for ages, just haven't got around to doing it yet....
