Hi

Does anyone have any drawings and dimensions for the front hub knuckle on a Sierra XR4X4

Also needing the correct dimensions for a standard McPherson strut and damper. KYB part number 334219 seems like the correct part version, but need further detailed build specifications for dimensions on it. likewise for the bilstein B6 variant 22-247483

What other stock and commercial shock brands can I use?
Monroe part number please?

I have the hub knuckle but no shock for it and having someone adapt or fabricate up something for me. Plan is to get a suitable strut shell and fit a damper insert to it? Anybody done this before

Purchasing from the UK / Europe and exporting will be a costly affair so looking at viable options to make up here in S.Africa

Any info or link to other posts will be good

Thanks

 

Does anyone have any info regarding the above. Has anyone made up or tried adapting bits and pieces together to make it. Just looking for the standard setup for now.

The b6' Fronts or any 4x4 shock strut are way out of my budget range for importing out of UK/EU to S Africa. It will be way cheaper to adapt something from possibly another vehicle or are these front Struts unique to 4x4 models

Cheers

 

The bottom of the strut on a 4x4 is 51 mm in diameter. This is a size that is quite common, so you might be able to find other shocks that fit. But you also need to take into account the total length and the stroke of the damper. You don't want the damper to bottom out or the wheel hitting the arch on big bumps.

I have been thinking about using Bilstein inserts for an Escort mk1/2. You can get some strut cases and build your own coilovers that way. But in the end that will be a lot more expensive than getting a pair off the shelf dampers.

 

Thanks Marc so in S.Africa there is no standard 4x4 oem equivalent off the shelf items available for xr4x4 hubs I would have to buy and import which is very costly because of size, weight and commodity type hence why I'm asking about alternatives for cases and inserts.

What would be an example on a standard length of a strut shock fully extended / travel to near bottom out and then to measure damper rate without it being it fully assembled considering using a standard coil spring setup. And then maybe a fully assembled part from bottom of shock to first nut and bearing and then full length.

Is the bottom of the shock tapperd to allow seating into the hub shock mounting hole or is it round and square?. These are the kind of details I'm looking for.

Do you know of any suitable strut case examples.

Cheers

 

The shock is just round and has a tab on the side that is the end stop for going in the knuckle. There should be plenty of pictures on the web on how a standard Cosworth 4x4 shock looks like.

The body of the 4x4 shocks is about 360 mm long and has a damper shaft of ~175 mm long.

I was thinking of making struts using this:
strut cases

And then using some 40 mm short inserts for an Escort mk1/2 like these:
40 mm inserts

The only 'problem' with the Escort inserts is that the thread at the top is very short. It's too short to be used with the standard Sierra top mounts, so you would need to use solid top mounts with a spherical bearing. Better would be to fit inserts with a longer thread to use the standard Sierra top mounts and roller bearing. But I can't seem to find other 40 mm inserts.

 

Indeed something to think about almost a lego assembly could be an option. So just to be sure what is the distance between the bottom of the shock and the seating or perch ring, what is the thickness of this ring outer diameter then the distance from the ring to the top of shock body

Is there any construction data of a generic 4x4 shock / strut ie fully extended full compression, what load it can handle, the correct spring rates and type etc

Thanks Marc for your help

Cheers 🍻

 

I found somebody locally who can build up something for me, so I'm needing some measurements from anyone please. Front 4x4 shock struts. before going off on a tangent as each brand or maufacturer has thier own specs. I need to know in the ballparks and can be based off the stock items or a range can be given. this will be for a fast road setup using a 2.9 V6 variant 4x4 setup



Length A mm=?
Length B mm=?
LA+LB = 360mm

Length C mm=?
Length D mm=?

Length E1 mm=?
Length E2 mm=?
I also need to know when the rod is fully retracted, how much is sticking out, the bit until the bottem end thread starts

Diameter A mm= 51mm
Diameter B mm=?
Diameter C mm=?
Diameter D mm=? (I also need a photo or picture of how it looks on the inside to see hoe the spring locates on the bottom of the cup)
Nut Size M = ?

Poundage / weight capacity Range =?
Comments: Figures provided as close to stock as possible This will be used for a 2.9v6 cosworth
Regarding Diameter D: The builder can provide a standard 2wd bottom cup




Any info will be greatly appreciated

Thank you.

 

Hi,
I ll try and find time tomorrow to go messure all that and take some photos. I have the original shocks (oe ford) of my sierra cosworth 4x4 up in the loft somewhere.

 

Hi there
so :
A = 23cm
B= 12cm
C= 18.5cm
D= 5cm

Diam A =51mm
Diam B= 150mm
Diam C = 22mm
Diam D = 12mm
Nut = 19mm

E1 = 58cm
E2= 41cm.

 

Thank you so very much this will aid me greatly really thank you

 

In relation to the bottom vertical bottom bracket, where the coil springs pig tail starts on the bottom cup would you say the notch is at the 19h00 position if the bottom bracket is at the 18h00 position?

And is tge bottom cup perpendicular to the shock body or at slight angle?

 

The start of the coil "pigtale" is at 8 o'clock in relation to the vertical mount.
yes the bottom coilspring retainer is perpendicular to the shock body.

 

Sorry 20h00 hours if you prefer in relation to the 18h00 hours of the vertical mount.

 

Perfect this is good stuff

You have any ideas on damping, force, ratios and rates?

 

No idea whatsoever of the oe ford damper and springs. Sorry

 

No worries your info has aided me none the less and i thank for that

If you compress the damper shaff, does it retract all the way in or does it stop with a bit sticking out? (Not refering to the threaded section) or how far does it stop or does it go all the way until threaded section?

Cheers

 

It goes down almost completly and stops about 5mm under the threaded section.

 

Hi there

Can you please measure along the raised ridge line from the shock body and where the pig tail starts to the inside edge of the cup in a straight line. Then the do same on the opposite side of that ridge. We want to see how far off center the shock body is in relation to the cup.?

The builder has identified and got a shock tube that I could use off opel/Vauxhall corsa




Cheers
