The repair shop told my friend that she needed new rear shocks and front struts, 4 - new tires and alignment. Shop estimate $1500.00.
I test drove it and it swayed side to side on the freeway, but didn't feel excessively bouncy. I thought that the shocks may not be the problem, but purchased new rear shocks anyway. Removed the rear shocks and they didn't feel bad at all.
Researched online and found this website. The recommendation was to change the bushings on the rear bars.
Changed out both lower arms (new). (No one had replacement bushing in stock and only one Nissan dealer had new bars only.) The front nut and bolt came out fairly easily, but the rear bolt near the rear end had to be cut out with a grinder and cut-off wheel which took most of the day. The rear bolts had to be replaced, none at dealer so bought grade 8 metric bolts. I guess after 200,000 + miles it's not surprising that the bolts were rusted in. Even spraying PB Blaster and letting it sit over night did help the rear nuts and bolts.
A buddy gave me a hand with replacing the top bars and that took about 2 hours. (New bars from dealer)
Now, my friend is not afraid to drive it again. No side to side swaying on freeways anymore.
I wanted to "thank" the members of this site for the recommendation!
