When the 4WD is turned on on my Honda Passport, it keeps getting knocked out, because the HI-LOW shifter on the Tranfser Case keeps getting bumped out. I have replaced the transfer case with a new one, but the problem still remains. If anyone knows how to fix this problem or has any suggestions pls respond. Thank You.

this may sound weird but I've seen this on a couple different passports having problems with staying in four wheel drive check both of your front wheel hubs and make sure that the axles aren't sliding out fo the hubs... can't guarantee this is the problem, just know I've seen it before.
