 Subject: 89 Dak 4WD problem CAD
IP: Logged
Message:
I have 1989 Dak 4x4 where sometimes the 4wd light comes on where I shift into 4lo or 4hi but the front hub is not engaged. I have verified that the driveshaft from the t-case to front differential is turning.
So I think I have narrowed it down to one of the
following:
1) Marginal vacuum from tcase to CAD
2) CAD is working intermittently.
I always thought the 4WD light indicated that the front hubs were engaged but there seems to times
where the CAD malfunctions and turns on the 4wd lamp even though the front hubs are not in.
Does anyone know the amount of vacuum pressure that should exist at the CAD?
Walt's 4wd page has been very helpful.

Any other suggestions are welcome.
Thanks,
Glenn

Also intermittently, when the 4WD shift lever is 2WD the truck stays in 4WD (which becomes a problem on dry roads).
I am confused at this point.

try this-put the shifter in 4hi,pull the vaccumm
lines off the front housing,with truck running see which line has vaccum,now shift it into 2hi/2wd see if the vaccum is on the other vaccum line,
if it did,nt change lines,then the vaccum switch on the transfer is the problem $18 dealer
if it changes lines everytime but the light won,t go out,the shift activator on the housing is bad,this can be tested with a hand held vaccum pump,these are $$$$$$$$$
