I have a 2008 Highlander Limited and carry a power chair on the back. This causes the backend to sag. What is the best way to prevent this; heavy duty springs or something else?
The power chair is on an electric lift connected to a 2" hitch with a swing away bar. The
combined weight is over 600 lbs sticking out the back of the vehicle. This causes a
noticeable difference in steering and handling. I'm surprised that the load capacity seems
so impacted by this setup. The rear end rides very low.
I have asked the Toyota service dept if they can add heavier duty shocks to my car but
they do not have any rated for the Highlander. I didn't think of springs and they didn't
mention that as an option either. Do you think that will help resolve this issue?
