E70 front springs removal?

[Wax5]

Can anybody can give me instructions on how to replace the front springs? Trying to put the 1.5 h&r springs?DIY

I'll be tackling this soon, but there are no DIYs for it.

After jacking up the side you want to work on, you'll have to remove the cowling under the hood for that side (or just do both). Then you'll need to remove the plastic divider that the cowl rested upon. This will allow you to get to the shock tower nuts.

If you have Adaptive Drive, unplug any wiring harnesses you come across. At that point, you can disassemble within the fender well. You may have to unbolt the sway-bar for more room. Once you finally remove the shock/spring, you'd then place it on a spring compressor, unbolt the top of the shock, lift and remove the spring. From there you reassemble with the new H&R/Eibach spring.

I believe you also have to remove the upper control arm, otherwise you won't have enough room to get the whole strut out.

Usually you can disconnect the control arm from the A-arm and shove them out of the way to make room for removal. I haven't looked closely at it yet, but I assumed this would work. If not, then yes, you're right, you'd have to remove a portion of the suspension to get the strut out.

finagle69, did you ever get around to installing your new springs yet?

[finagle69]

I forgot about this post. yes, I installed them a few weeks ago. Just the fronts though. The rear on mine is self leveling, so I used DIS to set a new ride height for the rear.

Install was pretty straightforward even with rental spring compressors.

The hard part was getting the top perch to line back up with the three holes. They're not equidistant, so there's only one way they can go back in.

Overall, since mine is the 4.8, it lowered about 1,75" in the front and I dialed in about 1.5" drop in the rear. I'll be getting it aligned at a shop tomorrow morning, then 12.5mm and 20mm spacers go on on the 4th.

crazy! we have the exact same set up going on! lol! did you use the rear link with the kit?

and sorry for the newb question but what is a DIS? don't you just put the new rear link and the car will adjust to that? mine too has the self leveling.

[finagle69]

That's not a noob question at all. DIS is a programming and diagnostic software that dealerships use for certain chassis coded cars. I didn't want to spend 100 on the adjustable links for something I could do myself with a little research.

Basically I set up a VM on my laptop and have DIS installed. Then you plug in an OBD cable and calibrate the airbags fooling the system into thinking its higher than it is.

Its easy to return to stock or set it at a different height also. Pretty cool. Very difficult to get the program setup though. Much more difficult than setting up NCSExpert for simple coding.

I see. so if use the link that comes in the kit, you don't need to make the DIS alteration correct?

HOw come you didn't use the links provided for the rears?

Did you figure out how to lower your headlight alignment that others were having issues with?

[finagle69]

Ah. I bought the Eibach kit which is four springs only. No links are included in the kit.

I believe the problem most people are having due to headlight alignment with the H&R kit is due to the front dropping more than the rear. This is exacerbated if its a 4.8 as the front drops even more with the rear being a 1" drop no matter what.

With DIS or adjustable links you can set the rear wherever you like. So I made mine pretty much even. This kept the headlight alignment similar to stock.
