Upper Control Arm Install

[nchiarel]

When torquing down the upper control arms, Bentley says to tighen them at a specific angle (don't have it on me), but all DIY's say to torque it at ride height. I replaced them all a few months ago using Bentleys angle method and just noticed my FR upper rear bushing is shot. I replaced that one this weekend, but am not sure if it was defective or if I should have lowered it to ride height and then torqued them. Do you think it's necessary for me to get in there and loosen them all, jack it up to ride height, and re-torque them? I figured the angle given by Bentley was compensating for them being installed while the car is not at ride height. TIA.

Random... How much difference does replacing the fuel filter make? I'm debating doing it this weekend since I don't think it's been done yet at 80,xxx mi. I got the car recently.

If your car is lowered the bentley does not apply as it assumes your car would have the stock springs.

I would torque it at ride height to be safe.

What he said ^

Yeah, I'd tighten at ride height. If you watch the inner bushing it stays fixed after it's been torqued down. I was just experimenting the other day on mine and tightened down at a lower height and then pivoted the control arm up. The bushing twists (as it's meant to) but you can see that it would always have positive pressure on it especially when the suspension compresses. As a safety, I'd torque at ride height.

Ride height, ftw.

Thanks guys, I am at stock ride height but I only used the angle Bentley suggested. I'll jack it up an re-torque them this weekend when I do my fuel filter and oil sensor.
