Busted CV Axles Dangerous?

I didn't see a thread on this topic, so let me know if I missed it. I replaced my suspension and the guy tore my CV boots, exposing the CV joint. A few mechanics basically said not to replace them or repack them until you need to since they are the original CV axles with over 170k miles on them...and there is no danger of mechanical failure that could cause me or my truck harm. They said at some point you will hear some grinding and know you need to replace them.

My questions to you guys:
-Can the CV axles seize up and be a danger to me while driving? How serious?
-If I replace them, should I go cheap or something like this: https://www.cvjreman.com/product-tag/9808/

 

I just did some wheeling in mine with a torn boot (very minimal) but looks like I might have done some damage. I get a nice clicking sound while turning and will be checking them tonight to see the damage. I personally don’t think it’s too complicated of a process to replace to boots. The OEM kit from the dealer has both inner and outer boot, the clamps and grease I paid around $46. The most difficult part IMO is removing from the differential, I’d recommend if doing yourself, invest in a hand hammer which should shorten the work to about 45 minutes. My buddies 04 Tacoma had some frankenaxles made with different components and he wheeled the hell out of it. I’ve been driving with a boot with no issues but remember, it’s a chance game your playing!! Best of luck!

 

This was really helpful!! Thank you.

 

Depending where you are, you could also have them professionally rebuilt. Most folks recommend not getting rid of your originals, and just having them rebuilt. Dont trade them for crappy aftermarket ones. CJV in Denver, CO and Axles Unlimited in Charlotte do incredible work. Had mine done at AU and they do all the work as well, removal, rebuild and install. For less than 1/3 price of dealership.
