Hey, I finally got my rear axle shifter working again, so its time I learn how to split shift. I've read as many threads as I can find, namely this one: https://www.arboristsite.com/community/threads/using-a-2-speed-rear-axle.98103/
One of the posters mentions that grinding while changing the axle is normal. I just wanted more opinions on this so I know I'm not doing anything wrong. Driving around slowly, splitting 1L -> 1H it seems to shift easily and I haven't heard any grinding. When I get on the road and try higher speed shifts is when I heard some noises that make my butt clench. I have an eaton fuller fs6206a transmission and a meritor A78 4.3/6.0 rear axle. The sun visor in the cab has shifting instructions, which seem to corroborate most of the information online (namely, be in High if you're split shifting), although it says to depress the clutch when going from Low -> High (everyone else says that Low -> high or High -> low just let off the accelerator and it should shift).
Can anyone give more feedback/advice? Don't wanna ruin this diff, as it doesn't seem like there is great parts availability for this medium duty meritor diffs.
