Should I replace springs at 215k?

I will be replacing shortly my front and rear struts/shocks on my 2000 528i sport with 215k. the shocks/struts are original. I just finished the rear bearings and noticed the springs have some of the coating rusting off but otherwise look fine. given the mileage and age, do springs have a service life? Really a safety question as I'm not interested to replace to lower or stiffen ride.

Measure the free height of the springs. If within spec, they are probably okay.

I'd be more concerned with the rust, esp if more than just on the surface. At minimum, get them cleaned up and repainted.

At 215K, I'd replace them for safety reason. I used to own a 2001 Honda Odyssey van, the Front spring broke at 55K. Glad it happened inside my garage and not on the highway!

Search forum for Vogtland springs.

I was searching around, autohausaz.com carries Lesjofors Front springs for $77, but they don't list rear springs.
I know nothing about Lesjofors springs, so will read some more later.

How many times have you replaced your shocks/struts with the same springs?

I wouldn't. My car has 216,000 miles and has surface rust on some parts of the springs. I have no worries about them breaking.

The Honda Oydssey broken spring seems to be a common problem.
I am not aware of any E39 that has broken a spring.

Spring is a tough call. It may last 50K, it may last 250K.

The problem is: when it happens, there is no prior warning at all. It is just boom.

+1, I have never heard of an e39 breaking a spring. Honda has an issue with springs. My 02 Civic broke a spring last week at 150K.

Au contraire; Colton from the e39source channel found a broken spring somewhere around 200k miles on his 01 540i. You can see it in the Strut Replacement DIY video around 32:40. Note that the car lived in the "rust belt", though.

The mechanic I had doing an alignment said the springs were sagging along with worn out struts/shocks. Thats my only preface of wanting to replace them.

How do you tell if your springs are sagging without taking them off the car?

Measure the distance from the ground to the bottom edge of the wheel fender. Compare this against the normal height. You'll need to search for that dimension. It's here somewhere.

From the Bentley workshop manual: Measure from bottom of wheel rim, to bottom of fender lip
FRONT
15" wheel standard suspension 22.8" Sport susp 22"
16" wheel standard susp 23.3" Sport susp 22.5"
17" 23.9" sport susp 23.1"

REAR
15" 21.5" 20.09"
16" 22.0" 21.5"
17" 22.6 " 22.0"

My shade tree advice is if the springs have not sagged more than 1" and the sag is even left to right, and you are okay with the look, I would just reuse them, assuming they are not in otherwise serious rusty condition or some other issue. Of course if the rear has sagged 1" and the front has not....that would look really weird and I would want to fix that.
Aftermarket springs are way cheaper than oem....unless you can find some good used ones somewhere...

I would tend to agree. As long as the rust is not terrible, I would simply clean (preferably media blast them), then spray them with zinc primer and paint. If you wanted to really go all out, have them powder coated.

I ended up pulling the trigger on the new coil springs. $240 for all four wasnt bad. Minimally if my springs are still good, I sell em as good used parts if anyone needs em.

Vogtland, B&G, H&R, Eibach.

I changed the bilstein coilovers and I ride on Vogtlands now mated to OE Sachs sport. Good choice.

Both front springs failed on my car. Each time in the driveway, one at 140k and the other at 180k. Both failures were at the bottom end and both were a result of rust.

You could see from the clean fracture plane that the failure was sudden.

The car has been a daily driver and the roads are salted in the winter.

Okay, so I finally received all of the parts I ordered but the issue is that the supplier accidentally shipped heavy duty rear coil springs.

Does anyone know if they will cause a stiffer ride? I looked all over and nobody really said whether or not for sure. They just said Hd springs are meant for people that haul stuff.

I dont haul anything but a set of golf clubs and an occasional case of beer.

One of my E39's front springs broke, it was also on the driveway and due to rust.

Around here a criminal about of salt is spread on the roads during winter, which no doubt was a contributory factor. The guys selling coil springs and new cars must love seeing the stuff getting spread.
