OK....So Below are pictures of my carrier bearings and i was originally going to replace them...but i think im going to need to hold off a bit so my new plan was to either fill up the cracking rubber with silicone or Liquid rubber.....Which one would be better....ive seen on some fourms this DIY repair and according to them it works good and no reason to see why it shouldnt....wanted to ask which one you guys think will be better...you can take a look at pictures below.
Thanks! (P.S how bad are these in the picture condition below....still get a few miles out of them in that shape or....just wondering)

hmmm....i mean its just rubber.....All it does is provide cushioning and hold driveshaft in place....as long as driveshaft isnt moving it should be good IMO....
Im not sure how hard it is to replace a carrier bearing because im not sure if im competentant enough to.......maybe someone with more experience on this fourm with this can help me out but i dont wanna start disassembling and then get stuck.....also dont wanna pay the shop becuase they will want 200 at least

Yeah I've never replaced parts like this yet, I'm sure repairing it thoroughly with whatever is preferred like flex glue or some paste .. let's just wait and see what everyone typically repairs these rubbery parts with.

Rubber ages with time, temperature, light, and begins to deteriorate. It not only holds things in place, but also reduces vibration and shock. The longer it ages, the more wear, tear, and vibrations can occur. Can lead to things not being aligned, losing power (because the power cannot be delivered fully), things of that nature. Which can all lead to more parts receiving more stress due to things being misaligned and stress points, etc. Domino effect kind of thing (although on a very miniscule level.)

If those cracks and tears is what you can see, imagine the micro tears that you can't see. All the more while it continues to slowly tear over time with weight, gravity, more vibrations via driving, etc.

It is something that should be addressed, but I wouldn't say it's the end of the world (compared to something like a timing belt.)

yup agreed just dont have the funds to fully fix it for now with fall semester of college coming up....lol.....funny thing is timing belt was replaced and is basically brand new in terms of wear....but the car was abandoned for about 5 years so im not sure where its at in terms of condition hopefully it isnt too dry rotted because that would be bad.....( 60k mile maint was done among all other mods....built block and trans before it sat for 5 years from 2018 to 2023)

In theory, they (timing belt) should be serviced every 5 years or 60,000 miles (kind of like an oil change, whichever X or Y hits first.)

But in practice, I mean if it was kept in a perfect condition showcase room, not subject to light/temperature changes like cold/hot/humidity, then rubber can almost last forever. Same reasoning it's possible to end up with 5 years old tyres, brand new, wrapped in plastic from tyre distributors.

But I digress, these are just normal wear and tear items - that yes, should be replaced when possible at a time in it's lifetime whether it meets X years or Y mileage, or Z visual inspection.

If you can't get to it for a while, you could try using products that stiffen/swell rubber like AT205

Mechanics and DIYers have been using it for years to silence bushings and revitalize seals. I don't know if I'd try it on something sensitive like a cam seal, but bushings and engine mounts like this would be fine.

pour some off in one of those little $1 travel spray bottles for airline travel and spritz the whole thing heavily. Let sit overnight and wipe away excess.

With the rubber all ready cracking like it is conditioners now will just make it fall apart in rubber chunks

It's best just to replace it
The bushing bearing inside has seen many miles as well
The rubber is just to cushion it
It's time for it to come out
Installing a new one really isn't hard at all
To reinstall
Pulling 3 piece driveshaft will have 2 carrier bearings best to do both same time
As well as inspecting the none serviceable U joints that you can't grease either

Or take an easier route and 2 piece drive shaft it with serviceable U joints that will come with 1 carrier that just slides in place

I thought about replacing my driveshaft quite frequently when I first purchased my car because I have these annoying vibrations and I thought the bearings in my drive shaft were shot but I've just been tolerating it this whole time...I am now slightly worried I have been just wearing out my other components faster so maybe it's time I pull the trigger on updating my drive shaft game!

you should!......check somtime when you under the car and try to just shake the driveshaft if it has a lot of play....the carrier bearings need to be replaced.....in your case you might as well upgrade the whole driveshaft
