Rear suspension trailling on the floor

[BWT]

Good Evening Folks

Just been away for the weekend first tow with this car V90 not exactly as expected The rear suspension seems to be a problem as when the caravan was hitched up the car was trailing on the floor the rear tyres were inside the wheel arch by about 50%. The nose weight was measured it was 100Kg so not overloaded.

Anyone else had this issue if so how did you solve it.

I do not want to take this out again until a solution is found as it made the normally ok steering very light.

Any help is greatly appreciated

Thanks

Something not right there. I have a v60 and with the tow ball / Hitch weight At 90kg the rear is down about an inch from normal. Do you also have a heavy load in the boot before hit hung up the caravan?

As Nick says something not right.

More info. might help.

How did you weigh the nose weight?

What else did you have in the car?

Was the boot full?

Were the rear seats occupied?

Did you have a roof box?

Does your V90 have the optional active \ air suspension?.
dis it return to normal when you unhitched the van?

Hi All
I will try to answer Whymans questions first
1) No roof box
2) Standard suspension
3) Nothing in the boot
4) Nose weight measure with a calibrated nose weight gauge
5) 2 adults on board total 24 stones
6) Nothing in the rear seats except the awning 30kgs

The nose weight stated by Volvo for the car is 110kgs

Uniqueue i have crawled under and yes it is a transverse spring and it appears to be some type of plastic!!!

Would changing the shock absorber help Bilstein do a shock which they recommend for heavy loads and towing B6 Sport I think its called

Thanks again

Rear suspension dampers have no effect on the ride height, that is the springs job .
The car is adequate for the job , take the whole rig down to the dealer let them have a look at it .

what happens of you sit on the edge of the boot does the car go down a lot? you would be a similar weight to the caravan i would think . or get 2 people to sit there.

The rear spring is a composite material first used on the 960 23 years ago developed with Lotus so well proved .
