Re-Lubrication. Voron 2.4 350mm

My voron 2.4 was well lubricated and working very fine, but also stinking of ABS fumes. I decided to clean it, and may have used more propyl-alcohol than necessary. Now there are some cricket noises coming from it. My guess is that the propyl-alcohol fumes may have reacted with the lubrication oil.

Is there a simple way of lubricating the linear rails without disassembling the machine? Before assembling the machine, I lubricated the linear rails in a way that would require to disassemble them and I would prefer not to.
