Symptoms :- Ride is very stiff, feel every crack and tar patches on road ... plastic interior is very sensitive now.
Checked no clunks or rattles from control arm or bushings etc . Kind of smooth ride on freeway but can clearly tell whether the road is leveled or not on interior roads.
History:-
Bought 3years back AWD 360deg version, now at133k miles, All 4 tires are kelly Edge A/S with 2017 stamp. They all have with dry rots now since COVID.Tires are at 33psi .Front shocks are stock and never replaced by previous owner, but no leaks,rust peels off bottom side of strut ( i live in rust belt state). Rear shocks was leaking.No crack in rear both springs. Front Passenger ride height is 1 inch lower the driver side, not sure its intentional design.Rear ride height same on both sides.
My repair:-
changed both rear shocks with OEM ones myself (DIY) 2021 summer,also changed to OEM sway bar end links ,Tie Rods to match original handling. Alignment done for new parts,rear was not affected.
Now no idea what is causing it to ride stiff.
So my question to NICO friends who faced similar issues before and learnt hard lessons :-
1.Changing rear both shocks (OEM ) cause a stiff ride?
2.Changing front sway bard links would cause suspension sensitive?
3.How can i if rear springs are worn apart from same ride height?
4.Can tire pressure causing significant stiffness.Should i reduce/increase to see any improvement?
5.How do we know if front shocks are bad if no leaks or broken spring , not able to find using bounce test.
6.Should i replace front strut for trial?
7.Should i get alignment if i change rear shock /front strut , is there camber/caster adj in this case?
Diagnosing this will definitely help forum and other Rogue owners in the near future.
