Yes....that tool worked great for separating the ball joints and tie rod ends. I actually found the cheaper one ( the black one only $20 Canadian ) worked better on the X as the fork part was a bit thinner. Popped them apart with ease and without damage to them. Some tools may require a bit of grinding to fit better on the X. I actually got lazy and just used it with an impact gun.
Perhaps a US member could recommend one available down there that worked well for them.
There is also this type that might work too :

Unless desperate...do not use this type of tool:

Usually works...but also usually tears the boot.
Some here claim to be able to separate the joints with a pair of heavy hammers. One resting against the side of the knuckle, and then a sharp blow on the opposite side with the other. I've not had much luck with that.....
After you do get the joint apart....I highly recommend servicing the joint. As you can see...there are no grease fittings on them...but rather "greased for life". But I dont reckon they intended a service life of more than 10 years or so. My joints were all okay with no play ( car had been sitting for many years )...but I popped off the boots... and inside was rather scary. No grease in sight !!! All dried up. Surely would not have lasted long at all like that. Clean them up inside and work in some new grease as best you can.
I think you said you you just got a new automotive multimeter ? Which one did you get ? But did you say it did not seem to test RPMs very well at all ? And which timing light did you buy ? I'm looking for a new one.
