the front ties bar rubbers?
The valance gets in the way, is it ok to use a UJ or will that lessen or increase the tourqe setting?

or is it a case of doing it up tight, and that bit more

[cal844]

i do them as tight as i can get them with an open ended spanner. I find it better to get the car raised by driving on 2x4 inch batons.

cheers

You can get these things, as I found out on here, called crows foot attachments for torque wrenches for things like this. I done mine up FT with a ring spanner in the end.

thanks for that :)

Iv just read on da google, that if fitting a crowsfoot, the tourqe wrench needs to be re calibrated/adjusted?

Just do them up tight. That's what everyone does. I've never seen anyone use a torque wrench on the front tie bars.
If you are worried about the nut coming loose, you can use a castellated nut, drill the tie bar and fit a split pin.

something I wondered might work, is undo the end by the hub....hold the nut with a spanner and find a socket that fits over the fork on the hub end...torque from that end ???

Never tried it but could work..

Other than that I normally just tighten them up :)

Steve, good lateral thinking. I reckon it might be a bit tricky to refit the tie bar to the bottom arm after tightening the front mounting up though.

As others have suggested - as tight as you can using a normal hand key. Best to use a ployurethane bush on the outside - but keep a rubber bush on the inside.......

No there is a formula for using a crows foot. The torque wrench should already be calibrated unless its been dropped. We have testing equipment at work to check the torque settings before use.



1. Measure the 'distance between centers' on the crowfoot wrench you're using.

2. On your torque wrench, without the crowsfoot, measure the distance between the center of the torque wrench handle, and the center of the square drive.

3. Determine the desired torque, and plug the values into this formula.

desired torque x torque wrench length
torque wrench length + crowfoot length = torque wrench setting to obtain desired torque


The formula will work with all units of measure, just be sure you are consistent. Example, for N·m, either express all measures values in meters, or convert to millimeters.


This is off the internet as i do not have my conversion book at home. However do as everybody does including me and that is do it up tight.

yea i done them up tight, anyhoo just wondered if it was critical do tourqe them cerrectly as i thought it might upset the geometry (over thinking it i spose)

O i do have the rubber n poly ones

Thanks for your advice, and technical doodaa about the crowsfeet

The nut bottoms out when tight so you won't tighten the load on the bushes or anything by altering the torque

So just tight as ya can then?

[mini-luke]

Depends how strong you are and how long of a spanner you use!

Damn it, im the size of a ewok and built like a ethiopian marathon runner

The nut should be wound down until it bottoms. I.e. you reach the end of the thread. Like a top fixing on a rear damper. This ensures the rubbers are under the correct compression. Then tighten the nut appropriate to the diameter of the thread. In ths case 7/16" UNF. From memory 72Nm. Or as othe posters have said, because when subframe s in ca access for a torque wrench is difficult, then best estimate of achieving that torque.
