This.
My 2003 Tacoma (yes, not quite the same) over the years has needed one A/C condenser due to corrosion ($100), one rear O2 sensor ($120), one A/F sensor (preemptive replacement $100), one muffler ($490), and one lower ball joint other than the standard brakes/rotors/drums. I do most of the work myself. The dealer did the muffler as the truck was there for the frame inspection/coating. I farmed out the ball joints. I had the shop replace all four while they were in there as they were all the same vintage. Total bill for that was around $750.
I did replace the shocks because they probably needed it. $350 or so and an afternoon.
Now, I did have a dealer quote me a muffler $1200 (part is $385 and 45 minutes labor), ball joints ($1200 total), they told me the oil pan was "rusting out" (it isn't), the steering rack was rotted out (it isn't), my tail light was cracked (it isn't), and several other things that were simply not true.
If you are going to almost any of the dealers around here, I think that might be your problem. So far I have found almost all to be... questionable.
