Should I replace the rear shock absorbers?

When I got my oil changed at Toyota 15k miles ago (I went to Valvoline for an oil change 5k miles ago), they stated that I needed new rear shock absorbers. Shortly after, I went to Meineke and they said I only need to replace the front strut assembly. They never brought up replacing rear shock absorbers. If I do need to replace them, how long can I go for? I already went 15k miles and everything seems to be okay. I am planning to sell it at the end of next year and I will be upgrading to a Prime, so I really don't want to fix something that doesn't need immediate fixing. Below is what is stated in the service history. Everything has been done except the rear shock absorbers.

*NEW ADVANTAGE LOF,CHECK TIRE PRESSURE,VEHICLE COND REPORT,FRT STRUT ASSY,FR UPPR SHCK/STRT NS,REAR SHOCK ABSORBER,*SPARK PLUGS R&R,YELLOW BRAKES FRONT,REPLACE FRONT BRAKES,*AIR FILTER R&R,CABIN FILTER,DECARB SERVICE,INSTALL 4 TIRES,*4 WHEEL ALIGNMENT.

 

Right now, I’m sitting just above 155k. The only thing the dealer did was oil change for $51. I was quoted at Meineke $850 for front strut assembly but found an independent shop with OEM parts for only $480. The front struts really needed to be changed because there was always one tire that had excessive wear and that was the front right tire holding all the weight. Toyota didn’t point out any specific problem with the rear absorbers, I think they are basing it off mileage? But other than that, it drives fine. I also did the spark plugs my self and torqued them to 15lbs ea with new Densos. Air filters off eBay for $10 lol. I don’t let the stealership touch anything except an oil changes. I go to several shops before I make any repairs that I cannot DIY. I anticipate putting on 30k more miles by the time I sell it. Around 185k-190k.

 

That’s good to know, thank you. I just commute to work 11 miles each way. 50% highway and 50% city driving.

 

Yes, I did an alignment and brand new tires and the excessive wear still kept happening on the front right tire. I rotated them and the same thing happen with the front right tire. I changed the front strut assembly and the problem went away. I should have done a bumper bounce test to diagnose. I have never heard of this until now, good to know.
