2006 Trailing Arms
I have a 2006 Mustang GT (97k) that recently while driving feels like the back end is slightly swaying. Took it into a shop and they are suggesting that the adjustable trailing arms get replaced and are quoting me $440 each.
This seems a little bit higher than expected and please let me know your experience. Thanks in advance

when they/you say "trailing arms" I assume they are talking about the rear lower control arms
they are widely available from both OEM and aftermarket sources ... below is one example -- the parts are around $100-200 per pair
generally you do not need the adjustable ones, unless you are super-critical about thrust angle or you have some other special requirement for adjustment
they are not hard to replace, you just need to be prepared to be working under the car and you need tools to be able to torque them properly, fairly high torque required

PS/Edit -- not sure why the link does not work; if you go to American Muscle and search for rear lower control arms for your car, you can find them

These Ford Performance ones are basically upgraded OEM (better bushings) and they are $150 for the pair
https://www.americanmuscle.com/ford-...ms-0511gt.html
But I would go with one of the aftermarket ones, they are beefier
There is nothing else in the rear suspension that costs anywhere near $550/each, except maybe the differential and that is definitely NOT a "trailing arm." Maybe their price includes labor to install, but that is a lot of labor to put the car up on a lift and remove/replace 4 bolts. Each control arm is literally a two-bolt job -- one on each end.
I think I would go to a different shop -- that one is obviously trying to way over-charge you; apparently they can sense your ignorance (ignorance is not a bad thing, it just means this is all new to you) ... you could call around and see if any are willing to install the lower control arm that you provide. Shops that are willing to install customer-provided parts are usually great to work with; because they are willing to help you in any way they can, instead of just driving up their price.

Thanks again everyone for the abundance of information.
Any issues going with the non-adjustable versus adjustable if the Roush rear lowering springs are installed?

no you don't really need adjustable control arms due to lowering .... but;
if you used an adjustable panhard bar to re-center the axle under the car after lowering, the thrust angle might be off a little bit; this would be shown in a 4-wheel alignment
that very small thrust angle is not a big deal and you would probably never notice or know if the alignment didn't tell you .... but the only way to correct that, if you want it to be perfect, is with adjustable lower control arms .... and you need to pay an alignment shop for a custom alignment to get them to adjust it perfectly (some shops might include that in a "standard" alignment, but most do not expect to be required to adjust this, they assume there is no adjustment because from the factory there is no adjustment)
I track my car and my thrust angle was off a little (like they all are) and I never even noticed
