where can I find torque settings?

[texaxile]

Hi,
I need to find the torque settings for the rear lateral arm bolts (all) and suspension on an 04 WRX Impreza. Does anyone know a reference which I can use which might also cover other vehicles as well?.(don't say "google" lol).

FWIW I understand all suspension needs to be torqued to spec when a car is on the ground, or on a 4 wheel ramp rather than with the suspension at full travel to stop premature damage to the bushes, am I correct in this?.

Thanks in advance and virtual Single Malt to all

Cheers.

That is indeed true for rubber "void bushes" as if you do them up on "full droop" they are permanently twisted on the road & it will shorten their lifespan.

Yes, tighten when on the ground and unladen. (Talisker 10 year old for me).

2004 Impreza Manuals This was hit number 3 on Google..

You need imp04_chas_2, page RS3 and RS4. RS3 is a diagram of the setup, RS4 has the torque settings (labelled on RS3 by T1-11)

He has full manuals on there to download.

......................................................... Might be a useful guide I hope.
Rubber has a property called hysteresis, which basically means if you deform it, it likes to bounce back to where it was. The importance of this in suspension is that you always need to tighten the bolts for bushings AT RIDE HEIGHT! Use a floor jack to raise the knuckle up to ride height, then begin torquing down the bolts. Both of the inner bolts are torqued to 74lb-ft. You'll need a crow's foot to do this and you'll have to torque the front one from the head side of the bolt (which is less than ideal). Make sure your witness marks are lined up! Torque the big long bolt to 103lb-ft. Once everything is torqued, drop the knuckle back to full droop and re-install the ABS sensor wire and parking brake cable brackets. Both of those little bolts get torqued to 24lb-ft. Reinstall the wheels, torquing the lug nuts to between 68 and 74 lb-ft ( I use 70, making all 5 nuts exactly even is WAY WAY more important than the exact value). Lower the car back onto the ground. Re-attach the endlinks to the rear lateral links, torquing the bolts to 33.2lb-ft (if you've aftermarket links, follow the manufacturer's guidelines).

You don't have to do it with the wheels on the ground (makes access fun if you don't have a ramp) - you can achieve the same result by measuring the distance from the arch lip to the centre of the wheel before jacking the car up to work on it, then use a trolley jack to raise the hub to match that when finished, while still having the wheel off so you can easily get at everything.

Edit - previous poster got there before me

Thanks so much gents, the guide and the info is exactly what I’m looking for.

I’ll have some help doing this, and will adopt the measure ride height and trolley jack approach when torquing the bolts, plus there’s an extra pair of hands to make life a bit easier.
