Hi I got a 2007 santa fe 2.7 gls When driving at hyway speed around fast sweepers it feels like the outside rear wheel ( left and right ) is squatting down or like the air pressure is low in that one tire but the they are at the proper psi .It feels about the same on the left and right . would new rear shocks help this ? they are the original shocks 100300 miles on them. About a year ago I hauled a trailer that was a heavy load for sure put a lot pressure on the rear end. THX for any tip or tricks also suggestion for replacement shocks I dont do alot of heavy towing. THX zzpop
