Thanks Chris,
Yes the truck is higher than normal, I can see 3" or so blocks on the springs.
I will double check how much of the splines are exposed,
There's slop on the driveshaft, it feels like the sleeve is too big for the driveshaft.
The 203 was running locked all the time with the front wheels hub locks unlocked, one of the levers was not connected and the 203 was left on the lock position, I assume this aggravated the situation,
If it turns out the 203 has a parttime kit, I will be running it on 2wd all the time, and will only use the 4WD when pulling the boat out of the ramp. I will have to make sure than the shaft does not spin on the sleeve.
I will take it out for a closer inspection.
Thanks again
