Post by Dr-Jon » Mon Jul 03, 2017 9:25 pm

took the wheels off yesterday to give them a good clean, and when I took the rears off I noticed the rear spring on the passenger side had snapped at the bottom, about an inch up. bummer so today I had 2 new springs fitted..
this car is a money pit...but i love it

Sorry to hear that OP. :(

I hadn't realised it is still an issue with E89s - you'd think they may have got it sorted by then. :headbang:

Having had to rotate a spring to stop a knocking noise, I can now see they are rubbish designed springs.
They use a barrel spring where the cars load bares down on a very small diameter with a pinching action, bit like compressing a small spring between your finger and it deflects sideways and pings out. It puts the load on the edge of the spring diameter and overloads it.
I bet very few front springs have broken, if any.

Had both of mine replaced as well couple of weeks ago, same thing. I did hear a knocking noise from mine when unloading the wheel.

just popped back to this thread... blimey I never realised this was such an issue.
I have a mate who is the manager at a Halfords Auto centre so i took it there as i wanted them replaced as soon as possible.
No idea what make they put on. But judging by the thread above it wont be long until they will need replacing again any way

That is bad timing OP. :(

But looking on the bright side, you won't be doing any tyres, springs or brakes again for some time - now you have got loads of time for love! :driving:

That took about 10 seconds to find on Google.
Having checked that site they do not list a Sachs brand rear coil but I have seen them there before and elsewhere.
A decent spring compressor you just might be able to remove the spring without dropping the shocker off.
