I'm getting ready to change front and back gear oil on my 2018 z force trail.
I was reading on the forum that it takes an allen wrench.Can someone tell me what size in case i have to buy one.
Thank you

They have different sizes but think the drains are 8mm. And 5mm is in my head for some reason for somewhere on some diff. Only use metric allens on these as SAEs will likely round-out.
