They're control arms, not wishbones.

Yes, all bolts will have a torque specified, but as you're bolting up the subframe at the back, I'd just give it a good erk and be done with it.

This assumes you're confident in your erk value, otherwise get a Haynes and have a look for the torque figure.  In my experience I have not had the control arm mounting bolts come loose.

If you have a torque wrench then you might as well use it, at least then you won't second guess your "erk"

If you need to ask the question, then yes torque them.

Provided you have the torque figure and you know your torque-wrench is calibrated accurately.  :wink:

You only need them if you stick with the mk2 bushes, if you go for the uprated tt rear wishbone bushes you dont need the guides. If id have seen this earlier id have told you to get the tt bushes before fitting the wishbones

If you noticed the rear wishbone bushes had voids on them, tt ones are solid rubber, make a decent difference without any compromise on comfort or increased vibration. Cheap mod also, only about 22 for a pair

They're control arms, not wishbones.

No, as they are a one piece item they can happily be referred to as a wishbone (in reference to the shape being similar to the bone found in a chicken, but then, you knew that  :wink:). A track control arm is usually part of a two piece assembly which consists of a track control arm and a radius rod/compression strut. That is all......

I guess VW are wrong using the term 'control arm' in ETKA then.  :huh:

whats the bit coming from the steering rack.

i call the inner bit the tie rod and end is the track rod end, should i call the inner bit a track rod or the end piece a tie rod.

doesn't make much difference i suppose

Guess you didnt notice the use of the word "usually" in my post when describing a control arm then? Either is perfectly acceptable to me and other trained Engineers around the world in this case, telling people they have it wrong when they don't though is not  :smiley:.

Right, Mk2 Golf uses McPhearson strut suspension system, and not Wishbone suspension! there is a huge difference! and should not be confused...
The "Track control arm" on a Mk2 only vaguely resembles a Wishbone, this is because it has 2 inner pick up points that attach to the subframe, reason for the dual mounting is to do away with a "Tie Rod" read cost cutting!

Wishbone suspension is normally found on more expensive, and especially on performance cars, and is on its way to being infinitely adjustable, its a more dynamic system...

The rod that protrudes from the steering rack, is called a "Steering Arm" this is attached to the steering rack via a ball joint, and is secured with a ball joint nut. The other end has the "Track Rod End" attached to it...

All these parts are designed to be sacrificial, meaning that they are designed to deform in a minor collision, or impact

Ah the joys of correcting the DH.....

Thanks for the description of a Mcpherson strut setup Thom, I would never have appreciated its intricacies without your input  :rolleyes:. Looks like I need to go back and re-do my degree then as I must have it all wrong.......

Anyway, Im off to tell BMW that they have called their control arms the wrong thing in their ETKA thanks to being enlightened by the suspension guru's that live here on this great forum. So odd that they should use both the term wishbone and control arm in it for exactly the same thing   :grin:.

"Track control arm" describes what it is, and what it does.
"Wishbone" has become generic, like Hoover

But with a Degree, you'd already know that.

Its like people calling a cam cover (gasket) a rocker cover gasket still, when their gti's don't have rockers.. But some do like to split hairs....! I'm guilty myself, but I've noticed most threads go way off track, and end up being an argument. Not what the op usually asks for..  Then there's people who know it all, but have never done it. I think actions speak louder than words, people just want to know a straight-forward answer most of the time on here...
