shock top hat cracked

Hi，folks,
I just find out my 2019 tacoma have a cracked rubber top hat ,
My questions are.
1 should I replace it soon?
2. can I replace it without removing all the assembly out？

Mileage is only: 34k miles.
I used ARB 2016-Present Toyota Tacoma Old Man Emu Suspension Lift Kit - Heavy Load 2" (OMETAC16HKSB),

ARB claimed that, mine rubt hat is OEM.
Thanks for confirming. After reviewing your purchase invoice it looks like the top mount was not included in your assembly as stated. This would mean the factory top hat was reused. Looks like this would need to changed as we do not provide the top hat.

Thanks

 

It looks like just the rubber bushing. If you can find a the right sized replacement and get that crusty old nut off, I would think you can replace where it sits.
Now the bigger question is- how many miles? It all looks fairly worn and you might be better off replacing both front shocks.

I am not saying it's not available, but Sparks doesn't list it, rather looks like it's part of the shock assembly,, probably for good reason, if one part is worn, the rest is too.

 

Thanks, it is pretty "new" three years old shock assembly, and ARB said my rubber bushing is OEM. see my edited comments.
I might try to just replace the rubber by removing only the top bolts.

 

If you are talking about a crack in the bushing, I would just leave it be.
