rear axle movement?

rear axle movement?
I have a 2011 mustang gt, 41K miles, my rearend makes a small but noticeable clunking sound at low speeds when going over bumps or changing directions, I'm pretty sure its the rear axle which when jacked up you can pull the wheels in and out a little, my question is how much endplay is normal, if any? And should I keep driving it and monitor it, or is it urgent? I'm doing an open track day in a few weeks and don't want any issues
thanks

Just for preventative maintenance you can do a differential service and replace axle bearings and seal. It's not a big project and decently budget friendly. All you need is a few hours on jack stands.

I had it looked at by the dealership today, and without opening the rear diff, they couldn't find anything wrong, he said the passenger side axle had a little movement, maybe a bent c clip, but they said it would take 4-500 just to check, how hard is it to open it up and check myself? it looks easy, but what do I look for when I open it up?

How axles come out without pulling C-clips is usually where the axle end breaks or axle twist in two between ends.
Every rear I ever had that had C-clips, and that includes several 8.8 Ford rears I have now as well as many Chevrolets back in past years .... and also, just about every one of 14 police cars I was assigned over a 31 year career (Plymouths in the late '70s and '80s, a '81 Ford, Chevys in the later '80s to late '90s, and CVPIs after '98 to 2010 .... and they got worked) .... they all had or have some axle end play .... they have to have some. Not a lot .... but some that you can feel if you jack the wheel up, release the brake, and jerk the wheel. You can hear it. 1/16" or 1/8" easy , maybe a hair more..... though it seems more if you aren't expecting it I guess.

Update: the dealership looked at service history and when they changed the fluid last yr, they didn't put any friction additive in it which is usually recommended, although he said the movement is normal, he thinks adding the additive will quiet it down, I'll let you guys know after its in
