Wobble....

1star · Oct 28th, 2021, 15:24

My 93 940 estate has just started to wobble.

By wobble I mean pulsate through the steering wheel at about 50-60mph, the weird thing is, it’s not always! Sometimes as I start a journey, sometimes it starts...gets worse...then stops!!

Any advice welcome.

I was going to say wheels need balanced ( weights can fall off ) but that would happen all the time when you reached 50-60mph

Have you checked all the wheel nuts are tight? If it isn't that it sounds like a wheel bearing - jack up the front wheels in turn and see if there is any play - also spin the wheels and make sure there are no grinding noises. If it isn't that check the rear wheel bearings the same way.

Check the tyres for bulges.

Sometimes the front wheels rotate at different speeds ( cornering etc ) so the bulge, or indeed the wheel wieght, on one side become aligned or mis-aligned with the wheel on the other side which leads to the intermittent imbalance.....

In addition to the advice already offered (front wheel bearings are very likely - not adjustable and expensive!

) check your tyres for being out of shape, literally! I've seen a pair of rear tyres (on an Astra) that were causing a strange wobble, back wheels removed and both tyres were "S" shaped!

Again it didn't always happen because at times they would become synchronised so one curve on one wheel would cancel the effect of the one on the other side.

Could be a ball joint...had the same recently...

Check your tyre pressures too. I've never had a car as sensitive as my 940 to unequal front pressures.

Hey thanks all, lots of stuff to try...I’ll work my way through the list.

I bought two new hub assemblies for the Valdez, complete with the big (36mm) hub-nut from Partsforvolvoonline for about £85 all-in. Admittedly they're for an ABS-equipped car but I didn't think that was too bad.

1) wheel balance
2) tyres out of shape (you can try swapping front to rear)
3) worn rack, tie rods, track rod ends or ball joints
4 worn bushes most likely TCA's but check all front bushes
