I can get a load of good QH ones from the Uk for reasonable money if anyone is interested, they are actually cheaper than the usual price for poor ones here, but the shipping causes the price to rise.
If anyone is interested in some I could organise a group buy deal on them
Roger they are not even close as I use to go through a set of QH's evey season and the TRW's I have had in the car for more than 3!
As far as the ID of the outer bush recess I don't care as the fit is nover a problem if you're using a decent bush
I have used these Uk supplied QH's in 20 or more different cars I have built in the last 3 years, and they have lasted very well, the same pair has been in my last 2 cars over 3 year period
They are not as good as genuine Ford ones but very good considering price
Not tried TRW ones myself, didnt know anyone who supplied them in the UK
Roger I will pop a bush out and measure when I get a chance.
Not really worried if people want them, its not like I have a load to sell, I just thought as I can get them for reasonable costs it may be worth trying to get some if enough people need them
Oh
And I have nevr seen any QH's with 603 on them, but thats not to say they dont come along, or that they may change in future, who knows??
With the limited choice of TCA's about now, it seems many brands are coming from the same production line.
The particular ones I have had the misfortune of buying, have oversize holes where the swaybar passes through.
The hole is around 3mm oversize in diameter.
The rubber bushes fitted as supplied do not match as they are still standard size. However they are glued with contact adhesive to prevent them from flopping around before they leave the shop. Obviously contact adhesive will not withstand suspension forces.
Currently available aftermarket urethane bushes do not resolve the excess clearance issue.
Additionally, the OD of the bush also has negligible support compared to the OEM part and the webbing thickness at the middle of the bush is thicker.
The downsides are reduced roll control, reduced bush roll force capacity, reduced bush brake force capacity, reduced brake force control and negative castor.
All the arms I have seen so far with the problem, have the number 603 on the arm.
Cheers
John
do QH have 603 on them?
MG
Well some things that were in a QH box do, among others.
The plan was new rebuilables not reconditioning old. JSA
John,
Where is 603?
Can u tell differences??
Usually markings on bottom tin cover on ball is give away
RM
On the vertical webbing of the I section.
Push the rubber out of the swaybar hole and measure its diameter.
Any sign of glue around the edges of the bush.
Cheers
John
I had the same problem just recently...
I hunted around but couldn't find any that had the same shape/size in the Caster bush hole as the OE ford items. I modified the hole to match the SuperPro bushes and OE ford detail. See the picture below.
Note that these also had the 603 on them.
The arms were overall VERY badly finished. The same as John discovered above the "webbing" on the arms I had was also thicker by about 2.4mm approx but it varied. The hole was oversized by about 3 to 4 mm, and again this varied between the arms.
I made some spacers that were a press fit into the arm and aided with a bit of loctite retaining compound. Each spacer had to be made a specific size to match the arm. The "webbing" in the arm was machined down to match the thickness of the OE ford arms (which was about 7.1 mm). This was extrememly difficult to do as it is very hard to mount the arm on a mill bed. Also the hole detail around the caster bush was too small so the SuperPro bush did not fit in properly so this had to be enlarged out slightly and neatened up at the same time as taking the thickness down to 7.1 mm.
This is my working out - but given that the arms vary so much not much use to anyone else.....
All in all a "bit" dodgy I know but I couldn't think of much else to do....

I've thought about doing something similar on the rubbish I bought. Concluded cost of buying and then fixing is not worth it.
Suspension place is looking at doing poly bushes to suit as the available arms with reasonable life balljoint all seem to have same problem.
As you say they are dodgy with variation from arm to arm. If joint QA is like QA of the rest of the arm I can't see them lasting long, contrary to claims.
Could be equally bodgy and pump gap full of poly-u in a tube, just need to find hard setting poly-u, maybe sikaflex panel adhesive poly-u. Goes against the grain though.
Cheers
John
John,
Here are better pics of roadsafe units It appears they have yellow glue on rubbers. 603 cast in eye beam recess too.
RM in Adelaide
There is a company in Christchurch that recos old ones by fitting new ball joints in them. I had some done last year. I have a record of who they are and how much it cost so will dig it out and post the details.
OK - The rebuilt ones were done by: HBI Engineering Ltd 31 Epsom Rd P.O.Box 11 024 Christchurch Ph +64-3-3483624
They cost NZ$65 + GST each to have the ball joints replaced in Sept 03. Not sure about the economicis of that now.
George Stock & Company here in Auckland www.georgestock.co.nz normally have new Camelot brand TCA's in stock. (they don't at present as I just ordered the last 3 pairs they have today) They're NZ$68.00 + GST each. The pair I already have look like quite good quality although I havent used them yet and have the 603 E4 L & R markings on them. I certainly can't see any dodgy glue on them. There are labels on the arms - Made in Taiwan!
Stocks have lots of other new ones as well including MK2 Cortina which are not handed - 30 odd in stock at present. The catalogue I got from them today has Camelot Design Industries Group PTY Ltd, NZ edition on it. The PTY bit is a dead give away that it's an Australian company and I noticed a couple of pages from the front their address is listed at 200 Mt Burnett Rd, Upper Pakenhan 3810 Victoria..... which..... is where i think your Roadsafe ones come from. Correct me if I'm wrong. Maybe we had an older batch here???
Hope that helps
Chris Chris
