Steering shudder

[Rafatak]

Hi guys
I have an E46 330i . It has 177000km on the clock. Recently I've experienced steering shudder when braking from 100km to 80km .below 80km ...no shudder at all. I've replaced the entire suspension including the lower steering coupler.
I've also fitted new front disc and pads about 10000km ago.
Still has a shudder.
Please can anyone shed some light on this .
Any advice will be greatly appreciated
Thanks

From experience, also on E46 330i...

Start with the wheels and tyres. Make sure the wheels are not buckled, and that the proper wheel balancing was done. Then after this you worry about front wheel alignment.

Next up is the brakes. Make sure it is the correct discs especially (considering you already replaced them) and that they not warped either, none of this skimmed bs...it never works out.

After this, the front control arm bushes.

If those 3 things are done, you shouldn't feel any shudder while braking or vibration while driving high way. I have now gone through this on 2x E46 330i cars...

Also get the front shocks tested.

So you have been driving around with this shudder for 10000 kms ? or has the shudder appeared recently ?

More information regarding the timing of the maintenance work and when the issue occurred might help us with a more accurate diagnostic

Thank you all for all the advice.complete suspension was done a week ago.
Control arms ,bushes , tie rods and rack ends, sway bar links all lemfoder and OEM lower steering coupler.
Bilstein B4 shocks and OEM mountings 10000km ago.the shudder started recently about 2weeks ago .wheels have been balanced and tyres rotated. What I haven't checked is if the discs are warped .thank you all once again for the responses

Just remember, when you get new brakes, you need to give them time. Like for 100-200km you drive turtle slow and brake soft. I dont know why, but you want to only lightly warm up the discs. Then after 100km you can take it up a notch, brake slightly harder for another 100km or so. Then eventually you can take it further and drive like you usually do...which for me is I like some speed.

ps. This 1st 200km is not highway driving, its normal stop-go driving as much as possible.

agree with above advice from @Tinuva , i would also double check the wheel balancing at another shop, preferably a shop that does road force wheel balancing.

Hey buddy,

Not sure where you located, but try taking the car to motor vision in Pretoria, they can do high speed balancing and are really good at solving these issues.

Giving advice then saying "I dont know why" doesn't exactly inspire confidence LMAO

Hahaha fair point.

I talk from personal experience. I am definitely not an expert that can tell you technically why it happens, just that is what happened with me on 2 different cars.

When I followed that specific advice from garage808 after having the discs replaced, they were good and still good year later and more than 10k km later.
