Hit 170k, I think my CV joints are wearing out.

[Mustang Matt]

I just hit 170k. Car is doing fairly well. I've had three rust spots fixed on the rear fenders before they got nasty. Powertrain seems fine but I'm starting to notice more vibration and non-sway bar clunking.

I mostly notice it when I make right turns or if I'm cruising around 60-70 mph and let off the gas to coast there's a bit of vibration.

Am I right in thinking it's probably the CV joints? I'm going to check the boots tonight and also see if it vibrates regardless of clutch position.

Looks like Rock Auto has the entire shaft and inner/outer assemblies for $50 each.

My understanding is that it's fairly straight forward to replace them. Just replace them one at a time and replace the fluid?

Thanks guys!
P.s. My rear AWR clunk fix brackets are still performing admirably!

Driving home, I'm not quite convinced it's the CV joints now. It seems inconsistent and it doesn't seem to necessarily be around the turns.

From 30-60 mph when I can make it happen, it's most prevalent when I'm giving it very light throttle or off the gas and decelerating slightly. Usually giving it more or less gas makes it go away. I tried popping the clutch a couple times and it seems to happen regardless of clutch position.

A bit puzzled. Maybe engine/transmission mounts?
I'm seeing some 4 piece sets for $130ish

Can I test the engine mounts by brake torquing it slightly and have someone watch to see if the engine is trying to jump out of the bay?
