4-wheel engaging

[gregor]

I was at work and we have 2003 f-350's with the 5.4 gas engines with manual hubs. When driving these trucks with the hubs engaged you are able to reach down and pull it into 4-wheel high with no problems. On my truck 2000 f-250 with 7.3 diesel if I try this it will not engage and you can hear it grind the transfer case. I was wondering if there is something wrong with mine? Or do the two trucks have different parts that would make this happen?

That sounds wierd to me it should go right in i have not heard of that.Some one will chime in and help.

[gregor]

Thats what I thought. But if I stop then it will engage with no problems.

how fast are going ? i'm not a real fan of engagement when moving

[gregor]

I could be going no more than 5-10mph. and it will do it, never tried any faster than that, afraid of breaking something.

didn't i read a post you made about engagement problems awhile ago trying to tow a buddy out of the snow ? was that ever resolved ?

[gregor]

Yeah I was having problems with the hubs, I got that one fixed. The 4-wheel drive works good, I just have to stop to engage it.

Hey Gregor, hows it going up there in Alaska? Don't have any problem engaging mine while moving, could be the linkage to the transfer case? haven't looked at mine to even see if they have linkage so just guessing there, or possibly the synchros in the transfer case?

i know that this might sound stupid, but make sure that ur not spinning the rear tires then try to put in 4.

It will grind if I am moving just a little bit, tires spinning or not.
