Outer Limits 4x4 Board

not sure if coincidence or not but i just got home from playing and noticed oil running out of the rear diff pinion seal. a quik check and the breather is bent at 90 degrees and the blue lokker hose is off. reattached blue hose and when lokka is engaged air runs out of the stuffed pinion seal. where the blue line runs in there doesnt seem to be a crush washer to hold the line in but it is still really tight? not sure if lokka still works but it all sounds good in there other than the air leaking out of the seal. does the centre need to come out to repair this or is it something simple.?

thanx guys racing this weekend so time is running out with the other 20 things to do.

when you fixed the line did you remove or loosen the bulk-
-head fitting on the diff?

not sure. i took the top nut that the hose runs through and then the next one that is threaded at both ends and cleaned it as it was covered in diff oil.
is that bad.???

i'll try post an exploded diagram from work tommorow, and you can show me wich bits you changed and or removed. if you need to get a replacement bulk head kit they are quite cheap.

thanx heaps. i left the last nut that screws into the diff housing on the diff, just took the other 2 off. will check out the pics 2mrw. thanx again

if you have the current style bulkhead make sure that the rubber o ring went in properly and is not damaged. also the airline support tube has to be good also [ seen people try to do a quick fix and leave these out sometimes]

if you have the old one make sure the olive has been reused and is in good nick, replace if suspect.when installing these ,the internal nut, item 8, should always be bottomed out before tightening fitting 5, if not you can generate an airleak from this. also make sure the tube has not been pushed back in.

thanx for the pic. pulled it out this arvo and parts 3, 4 missing altogether so i just ordered new seals and a new fit kit altogether. will be putting it back in tomorrow all spanky and clean.

thanx heaps for the pic it will help heaps tomorrow. printed 2 copies to keep.

i had a similar problem and it was building pressure in the housing and pushing oil out of the axle seals. it ended up being the o ring.

always wise to carry some of these items spare...you never know when that nasty log or hitch hicker is gonna ruin your day. you can upgrade to the heavy duty airline kit....extremely strong! glad i could help.
