Even the best T2's will have trouble with the cave wolf when he has a very bad spawn.... don't feel bad if you cannot kill him.
The first thing I would suggest is trying to not aggro the shadow groups in front of the cave, as when they get into the cave they will kill the spiders you need the kill the wolf.
My second suggestion: patience, patience, patience and even more patience!
In (most) spawns the wolf will wander to the cave by himself.
When he gets close, pull him with a longbow (preferably one with +20% ench so you dont need to switch weps).
I don't know in which order you do t2 but this is mine:
Start > open forge > get slaves > get hunt (wait for the shadows to lose aggro before entering the cave) > kill cave wolf if he spawns very close to cave > kill beach wolf > another chance to kill wolf if he's closer > go to khobay(if the main team is almost done with forge wait and do restore first) > if I went to khobay > return to cave and kill wolf if he is close > de restore > wolf if he still isn't dead > send mage .
In 9/10 runs I'll need to send the mage when im done with restore, but just send him when t1 need it.
In that order I will have 4 chances to kill the wolf, 4 chances in which he can be closer to the cave.
Sometimes, there's a spawn where there's no way to get past the shadows without aggroing them, so they will kill most spiders in front of the cave.
In this case I would suggest the following: 1)get summoning stones 2) buy a max damage q9 earth staff with enchanting mod and auto attack him (with ward on while using sliver on recharge).
Pull the wolf out of the range of the shadow monks and use either option 1 or 2.
With option 1 it will go fast, option 2 will be slow but you will kill him.
My last piece of advise: take your time, most pug run are 25 min+ ( I assume you are doing pug runs). If you got a slow main team you can take your time for killing the cave wolf but finish all your other tasks first before focusing on wolf if he has a bad spawn.
If you got a good main team, let them kill the wolf. For a good main team it is less then 1 min of work.
Hope I helped a bit
