Default Front Upper Control Arm Balljoint Boot

I recently swapped to my Winter tires last week and discovered that I had a torn pass side front upper control arm boot. Is it possible to replace just the boot and regrease it? I don't have any slop whatsoever in the control arm balljoint or in the bushings attached to the car's shock tower.

I was researching and found out that Toyota sells just the boot under this P/N

43324-39015

https://www.toyotapartsdeal.com/oem/...324-39015.html

Would this be the correct one I'd need for my 97' LS?

Or I found another company which I've used in the past to replace my front inner LCA bushings instead of buying new control arms with good success.

Looks like that boot is for a 4Runners UCA which has a serviceable ball joint. I guess there's a chance it may work but the LS UCA def not the same as a 4Runners.

AFAIK that boot is not replaceable. Sadly the joint will fail long term. Just keep an eye on the amount of play and replace before it becomes an issue.

You could buy something like that but in size medium ((Medium 12-16 / 30-38) original boot on 97' model is:36mm / 13mm):

PS: keep in mind the fastening ring won't fit...I used some wire.

I was hoping to use something from a dealer since the rubber quality is far superior than aftermarket. Hell my original lower balljoint boots still had the boots intact. I stupidly threw those out a few months ago when I moved.....I could've used those boots! oh well.

I saw somewhere a guy used some boots from a 99 Accord V6 on his SC430...for 8 bucks for a pair or something like that. I'll give that a shot since there's a Honda dealer next to my work.

I had success replacing just the boot (albeit on my Hondas as they sell boots separately) but as PD said it will fail eventually so a close watch on the joint is important.
make sure to clean the joint well, removing any debris, and use quality grease before slipping the new boot over (assuming you found a correct replacement boot).

as for the bushing, it's the same story. if you can get the old one off and new one pressed in you're golden. don't forget to load the suspension first before torqueing to spec to ensure proper bushing rest.

I went to the Honda dealer today and those Accord V6 ball joint boots are only 4.95 a piece so I'll order some up most likely. After measuring the outer diameter of the boot, it was about 48.5mm tapering down to about 30mm at the knuckle with a double accordian boot.
