What torque for suspension parts?

[Martin.]

Now I would normally just do everything up by hand using judgement and check it after a few miles/days etc. But thought I may as well ask the question and get it right if possible.

So could someone please tell me the correct torque for the following suspension bolts/nuts:

1) Front strut bolts.

2) Rear strut bolts.

3) Wishbone to subframe bolts (one the front one there's two bolts, one after the washer and then another after the support bracket)

4) Hub pinch bolt.

5) Caliper bolts

6) Ball joint bolts

7) Outer ARB bracket bolt

8) Inner ARB bracket bolt.

9) Track rod end bolt

10) Inner track rod bolt

11) Front top mounts

12) Rear top mounts

Cheers :cheers:

Doesn't matter if its torqued or cross-threaded, tight is tight. iirc

Very helpful lol.

 

[Budgie]

Tight enough so they won't come undone. But not too tight that you'll regret it when you come to take them off next time

So just by hand is good enough then yeah.

As with wheel nuts.

So could someone please tell me the correct torque for the following suspension bolts/nuts:

1) Front strut bolts. 175nm

2) Rear strut bolts. 175nm

3) Wishbone to subframe bolts (one the front one there's two bolts, one after the washer and then another after the support bracket)

4) Hub pinch bolt.

5) Caliper bolts. 60nm i think

6) Ball joint bolts. 42nm

7) Outer ARB bracket bolt

8) Inner ARB bracket bolt.

9) Track rod end bolt. 37nm

10) Inner track rod bolt

11) Front top mounts. 20nm

12) Rear top mounts. 20nm

That's off the top of my head.

FT for smaller parts and QFT for bigger parts.

Straight out of the Renault manual iirc

 

[mark123]

Search for a link to the manuals on here. All the values are in there and they're largely different to those quoted above...

Yep, the bigger ones like struts to hub, i wang up with the gun, then check with a breaker bar. Don't want those coming loose, lol

Everything else, i do with a 1/2" ratchet.

Yup. Although I got my post mixed up. QFT and FT should have been the other way round.

Awesome thanks.

Still can't fine the torque for the 3 wishbone to subframe bolts??

or the pinch bolt in the hub!?

trying to get them done and dusted tonight so any quick replies be much appreciated

cheers

Lower arm pivot bolts are 90nm

 

[Martin.]

Is that what they're called ☺️ Thanks mate.

 

[JamesBryan]

What's the pinch bolt in the hub you're on about, i'll see if i can find the torque.

Cheers mate.

Its the bolt which which holds the ball joint tight in place

 

[JamesBryan]

Is it the one that clamps around the bolt?

Called Lower arm balljoint clamp bolt, if so it's 55nm

Not entirely sure to be honest. The ball joint pushes into the bottom of the hub. And this bolt holds it in place I guess.

 

[JamesBryan]

Yeah, it's that one i mentioned mate. Ball joint into the bottom and bolt goes through. 55nm

 

[Martin.]

Yeah, it's that one i mentioned mate. Ball joint into the bottom and bolt goes through. 55nm

So 90nm and 55nm thanks a lot mate.

You've not got the ball joint nuts to hand there have ya lol!

What ive written down from that link is 40nm. That can't be right for them surely!?

 

[JamesBryan]

The 2 nuts that hold the ball joint from underneath the arm?

 

[Martin.]

That's the ones mate yeah.

 

[JamesBryan]

That link says 42nm, but my guide says 75nm.

 

[Martin.]

That link says 42nm, but my guide says 75nm.

40 odd seems too low for these don't you think!??

Is there a torque for the wishbone support bracket screw? The one which goes into the arch face.

 

[JamesBryan]

Not sure on that one mate :dapprove:

 

[Martin.]

Not sure on that one mate :dapprove:

Packed up for the eve now though as he light is disappearing fast. Thanks for your help buddy.

 

[JamesBryan]

No worries. I'd just do that support bracket tight enough to what feels good.

 

[Martin.]

Yeah that's what I did. Still need to do the hub pinch bolt and the ball joint bolts.

Think i'll go with your sheet and do them at 75nm for now. 42 seems too low to me.

 

[JamesBryan]

Yeah it does seem low.

 

[Budgie]

You're overthinking this.

If you don't want it coming loose, wang it up.

 

[CamMoreRon]

Not as simple as that, really.. wanging things up can sometimes do more harm than good, and I don't just mean in terms of being able to undo them again. If bolt torque settings are available, which they always are if you know where to look, then they should always be used.

If you have any level of mechanical sense, you'll be alright.

 

[CamMoreRon]

9/10 times, yeah you will. I just don't get the attitude whereby everything is done QT / FT when torque wrenches are inexpensive and settings are freely available. You don't see people doing head bolts up QT, yet for some reason safety-critical parts like brakes, suspension and wheels are fair game. Hhhhhhwy?

 

[Budgie]

I don't do everything QT/FT FYI, I nip everything up. That'll do

 

[Mr R.]

Finger tight ftw.
