Changed the rear axle CV joint half shafts. The clicking was finally getting to me.
Got only about 24K on the "Lifetime" Duralast AutoZone units, which they replaced for free. Originally bought in April of 2017.
In all fairness though maybe they are sub par parts and maybe all the 1200 mile trips I do hauling a 4,000# trailer might have been a bit much for the budget parts
It was a good post-Christmas automotive pilates workout
