it's much better to just get a exchange axle,,with two new joint,s,,you also get a lifetime warranty with about all of the now day,s,,and it,s lots less messy too,,changing those thing,s may be a big mess, ,hope this assist you some.

beena mechanic for 35 yrs.

just the damagd one ..if it aint broke then don't fix it

If one is damaged, chances are the other is not far behind. Check the condition of the other but think about changing them both simultaneously.

you have to change both just like tire in pairs

When you take your car in, most of the time they'll tell you to fix both simultaneously. If you're doing it at home, I think you may want to change both. My husband changes lots of that stuff and he generally changes both. That way, we do not have to worry about the other one going bad afterward, then we'll know the date that they both were put on. But, if you do not have to do it with both now, then that's totally up to you.

The work is lots less based on the car if the complete axle is replaced than just a boot.

Normally, the boot and adding more grease is the standard procedure, but I have found that installing a totally overhauled axles will give part of mind for the owner and the mechanic. When they are overhauled, all the bearings, seals, and grease are replaced so nothing should go wrong unless your technician made a mistake or there happens to be a make defect.

Parts are cheaper by replacing just a boot, but most cars I have seen have had more damage than the boot, typically just the cv bearings. This happens from driving the car with the boot torn or open for some time period.

My advice: Change the complete axle. it'll save you time and it is only a $10 $40 difference from a boot and a totally overhauled axle.

You gotta go with both if you may be able to pay for it. be sure you have a proffesional mechanic do the work at a shop.
