Title: Low speed wobble
Post by: frostbite on 04 April 2017, 23:25:57
Hey

Since I have had the saloon, it has had a slight wobble
and can only be felt going less than 25mph, I really felt it the other day after I took my dad out for his birthday and we had a bite to eat. We had a short journey home but was in traffic and it really churned my stomach

what could it be?

Is it a wobble or a shake?
Can it felt through the steering?
Is it in a straight line or turning?
Does it feel from the front or the car or through the seat of your pants (back end of the car)?
I think a bit more information is needed and then may get you the answers you want....

The steering is solid, even with the worn wishbone

I think its the rear, It feels as if my bum is dancing in the seat .

Could be buckled wheel or out of shape tyre

It does need new boots, I will check the inside edge for flat spots

Worth checking also the rear diff mountings or subframe mountings for the rubber becoming unbonded.
A slow speed 'wobble' is also a symptom of loose wheel bolts!!!!!

I second that.

Out of shape rear tyre makes it feel like its wagging its tail, usually more noticeable on acceleration.

Well as I drove to work, I was leaning on the armrest and had my left hand on my lap

And it was jiggling lol in a circle

It is noticeable when accelerating from a standstill

I will check the wheel bolts

Yes it can be a damaged tire, maybe not even visible to the eye. I had exact same symptoms with low speed wobble but nothing at higher speeds and it was worst when accelerating from stand still.
One of the rear tires had some damage.

Try swapping front & rear wheels over and see if the problems moves to the front - assuming its nothing which is obvious to the naked eye.

Check the conditiob of the rubber propshaft couplings. This can cause wobble on low speeds, although notbsure it will be present from standstill.

Could be loads of things, easiest place to start is by whipping the wheel off one by one and replace with the spare and try and pin it down, if not wheel, tire related then move on to to the other suggestions.

I will check all I can

thanks

Also would a snapped coil spring or collapsed shock do the samething?

I doubt a broken spring would cause these symptoms.
I've got self levelling on mine, and when I've broken a spring I've not known about it until I have jacked the car up for some other work. This is because they usually just break on the 'pigtail', and the main body of the spring is still doing the majority of the work being stronger. If a shock has failed due to a leak (usually as a result of a pin hole from corrosion on the lower section by the gaitor), the car has generally dropped slightly on the affected side, and the shock knocks over uneven surfaces.
Your car will just have standard shocks, so it should very simple to check whether one is knackered, either visibly leaking, excessive bouncing on that corner or with a knocking over rough roads.

Last week I went DOWN a massive pothole in the lorry lane of the M62 at 70 mph.  The car nearly fell apart. Now I have a low speed wobble, but it's FINE at anything above 20 mph.

Sorted the wobble, it was a disturbed tyre

Had a bald patch and huge egg, couldnt belive it
