Taking bump stops off?

coldsmoker · Jul 11, 2014

The series 3 has a very harsh ride, speed bumps are a nightmare. Whilst it was up on the ramp for some works on the dif I realised that not only was she very wonky (knew that already) but that the off side rear bump stop was pretty much touching the axle even at rest.

Whilst saving up for new shocks and springs the guys at the garage suggested taking the huge bump stops off. Seems a reasonable plan but could it do any damage?

Input appreciated.

Well they're there for a reason. You could always take them off and find out why...

They're not standard bumpstops, the original ones would have been half the size of those.

Are they bump stops or spring helpers? As above, they ain't standard...

If it's resting on it already removing it may make the spring sag further

They look very non-standard... might be time to fork out on some GBSprings parabolics if its sagging. The springs on there look to be paras but maybe they're the crappy ones that were around a few years ago that were made out of recycled cheese

Defo bump stops and not actually touching at rest, so the spring are holding at the angle shown. Not standard for sure and they are enormous. The garage seemed to think it was a obvious and good thing to do and they are well regarded specialist, but thought I'd ask here before taking them off...

Had a chat with GB Springs and it's on the list of things to do in the Autumn, but as a interim measyre to improve the ride is it worth trying?

are the two bubbly bits joined together?

might be possible to cut them in half as a compromise

coldsmoker · Jul 11, 2014

@honolulujoe, good plan, will try that.

arb78 · Jul 11, 2014

I agree with cutting them in half, Id rather do that than have the axle hit the chassis.

trax · Jul 11, 2014

look like spring helpers to me either for heavy loads or due to your saggy springs

edit: and a quick google shows... i am probably wrong and they are truck bump stops

why not rip em off and stick standard on and see how the springs react.. they might have been put on to hide that dodgy spring

coldsmoker · Jul 11, 2014

@trax wouldn't spring helpers be attached to both the chassis and the axle? These are only attached to the chassis and appear to be just lumps of rubber rather than having a piston in them. Springs indeed saggy though

@trax? What the hell is this? Twitter?

coldsmoker · Jul 11, 2014

Just so you know who I'm replying to, your all so good at replying to my minor woes

@coldsmoker yeah think i was wrong #theshame #allifeistwitter

Thank you all :hug:

Will try cutting them in half and see how I get on.

(will try and improve my etiquette too).

coldsmoker · Jul 11, 2014

Well I've chopped the bottom "doughnut" off as sugested and given it a clutch around the block where most of the speed bumps and humps are and it's made a considerable difference. Those that warned me off taken them off completely were probably right, but halved they can still do their job but there is a bit more travel.

Still need to keep saving for the new springs though...

You could always remove them and fit proper ones, they're only a fiver an axle!

As they are now they do the same job as the proper ones and its only cost me half an hour with a saw.

NiteMare · Jul 14, 2014

as already suggested they are spring assisters

Aeon spring assisters

if you remove them you'll need to take an angle grinder to your axle to remove the cups that have been welded on for them to contact and stay in place, if you don't grind the cups off when you change to standard bumpstops you may find they wear oddly

bump stops are hardly used unless you're offroad.....odds are they'll be fine for the rest of eternity
