Front lower ball joint, replace boot or whole thing?

I noticed the boots on both lower ball joints are starting to leak. Should I just replace the boots or the whole ball joint? I've not noticed any issues, but honestly I don't know what sort of symptoms a bad lower ball joint would exhibit.
This if for a 1999 tacoma, 4wd.

 

It depends how many miles do you have on them might aswell replace them if you have alot

 

1st gens have a lot of issues with lower ball joints. I would just replace the whole thing. Better safe than sorry.

 

Only the very originals. The design was changed and all are good now.

 

True. But my statement still stands as a good idea

 

while on this topic, if my lower ball joint boot is busted and leaking (2nd gen 2wd) is that replaceable or do i have to replace the whole ball joint?

 

Rockauto.com lists the lower ball joint separately. Will need to have a machine shop press it in/out.

 

thanks man!

 

Yea there was a recall in the lower ball joints

Op should go check if his truck has had the recall done or not if it hasn't been done free ball joints!!

 

I have around 110k miles on the truck. Unfortunately (?) the only recall for my vin is some tow harness wiring deal.
