whats up everybody im new to this forum and have a question about my 1997 ram sport. Went mudding the other day with a bunch of friends and they say not either tire was spinning in the front. Now i know these trucks come with ****ty a** open diffs but should'nt 1 tire be spinning??

Nice found was i was lookin for.damn vacume problem.look like im gona have to buy the cable posi

 

Yup, that would be your best bet. Its a little spendy but it won't leave you stuck in 2wd.

 

Well its gonna be awhile until i will beable to get the cable posi...moneys a little tight these days.So i just got done looking for the weak link in the vacume lines.I did find one that was completley un-hooked.Hooked it back up and it still wont go in 4wd?what is the vacume excatley for??my dad seems to think its for the hubs.i know this has probably been asked but i cant find the answers.any help would be MUCH APPRECIATED.

 

Its for the CAD (central axle disconnect). Basically connecting the pass axle shaft to the *hub*.(if im wrong here correct me someone). Odds are either you have a leaky vac line or the switch is bad(most common).

 

Technically it connects the two passanger side axles together with a collar. The outer shaft is always connected to the hub.

 

this is not an uncommon problem, the best bet obviously would get the posi-lok, but its not needed, luckily the 4x4 is actually easy to get workin again. I re-did my vacuum lines, and now right whe i pull the shifter it immidiatly goes into 4wd, and when i push it down it disengages right away. doesnt matter what the weather is either. always works perfect. but i dont shift on the fly. i stop, put it neutral, then shift it into 4x./ out of 4x

all in all id just re do all the vacuum lines

as for the tires spinning, i have open diffs, with 4.10 gears and with mine, it actually goes back and forth between the front tires on which one spins when i hammering, if im going slow, my DS tires s the one spinning
