Front and rear shock replacement

Can anybody direct me to a tutorial on replacing the front and rear shocks on my 645?

I have H&R lowered springs with original shocks and planning on upgrading to Bilstien sports any advice on this setup?

Thanks

The only help I can offer is to advise you to check the E60 5 series forum. I think it's more active than the 6 and since the cars are mechanically similar you may find some info from someone who has done it. Front should be same process and I assume the rears would be same or close enough.

just installed my lowering spring with a friend who has a shop with the proper tool. you definitely need a spring compressor in order to remove the spring from the shock in order for you to swap the shock.

to remove the front, remove the three nuts (10mm if i remember right) at the top of the shocks (inside engine bay), and then two bolts behind the wheel hub (one 16mm and one 18mm). then you need to push the shocks down from the wheel well in order to get the top out. you need a lot of wd-40 and muscle to slide the bottom part out.

rear ones are easier, three nuts on top and one bolt at the bottom and it falls right off.

once you get all four off the car, you will need a spring compressor to remove the struts from the springs and install new struts.

let me know if you need to know any detail, i'll be more than happy to help.

Great info, what shocks did you go with?

I purchased my 645 a couple of years ago and the previous owner had already installed the lowered springs but keep the stock shocks. When I ordered new Blistiens they recommended to install the sport shock.

Thanks for info, I will be installing the new shock as soon as they arrive

I didn't replace my shocks. I only replaced my springs with H&R lowering springs

^^^ How's it handling for you? Always thought you needed different shocks with lowering springs.

the front shocks do come out easy if you insert a small chisel or a screwdriver into the slot behind the shocks and just give it a little tap with a hammer then the shocks will lift out very easy.

Try this. The guys over at the M5 board have an extensive write up on how to do it. Quite simple actually if you have the right tools.

It's always my frim belief that if you have the oppertunity to do something, do it. Since you already have it apart and if the bearings are not a bank breaker, I would replace them as well. After all, you won't have to worry about this again for a very long time.

Makes sense, I have notice there are a few manufacture offerings when it comes to the strut bearings and the price difference roughly 30 to 50 bucks each bearing, any recommendations on which one to go with. I have not check with the dealer on pricing on the OE part as I'm sure it's up there.


Thanks
