Rear Suspension Components - What Aged Components have you Swapped

[jsoto]

Hi All -

At 100K, a see a lil oil on one of my rear shocks.
Plan to swap the shocks out.

Rear Upper Control Arms were done awhile back.
In looking at my last 2 alignments (all within the last 20K), the rear alignments have always been in spec.

It's too cold right now, but when it warms up, I plan to jack her up and give it some wiggling to see if there's any play.

I'm curious for others, what have you done on your rear suspension just due to age or fatigue ?

Thread Jack. What causes caster to not be in spec. In reviewing my last 4 alignments, even one right after a complete overhaul of the front suspension, drivers side caster is always at 5.5
