14 bolt seal question?

[Fancy]

So i was installing my new backbone kit from DIY4X and after i noticed a leak from between the pinion retainer and the housing. My question is what is it going to take to fix this?

Can i just remove the six bolts and pull the pinion retainer/setup out a little to get some more liquid sealer in there after i prep both surfaces and then torque it all back down or will i throw something off like the preload? and if so is there a trick to backing out the pinion retainer/setup?

Just don't want to screw anything up before i attempt to seal it up.

Thanks Guys!

according to the GM service manual, the crush sleeve should be replaced when the pinion is moved....that being the case I think there are more than a couple who have done it without replacing the crush sleeve.
PM 4X4high or Blazinzuk!

If your leak is at the pinion support/housing area, you can remove the pinion support by removing the 6 bolts, clean the shims the best you can without loosing them, and re assemble them in the same spot and torque to spec do not add sealer to the shims, it will mess with the pattern.

Otherwise its most likely a leaky pinion seal which would require the crush sleeve be replaced, or count the turns/threads on the pinion shaft and install a new pinion nut. Also add thread sealant to the splines of the yoke, ive seen some axles sweat there in the past.

Interesting!! ya it is defiantly in between the pinion retainer and housing and there is already sealer added its orange. If it was the actual pinion seal wouldn't it be leaking from farther up? I couldn't tell there even was shims there and any diagram i look at makes no reference to shims? dose any one have a picture of them or is it pretty self explanatory.

the shims look like a hexagon with 6 holes for the bolts, they go between the pinion cage and the 14 bolt housing. These set the distance on the pinion in and out per say...if there dirty or have debris on them, they will sweat or leak gear fluid.

Ok cool so basically when i pull it out keep track of them clean them and put them back and that should be good. Ya it is not a bad leak more like a sweat. not enough to drip.

Thanks For the help

no problem, torque spec is 65ft/lbs...

Any tips on getting the whole assembly out the easiest

Remove the d-shaft, then I hit all 6 bolts with an impact, and pull on the yoke, the whole pinion support housing should separate, then I carefully watch the shims and keep them in order. Make sure you clean both sides of the shims and the housing and the pinion support...It can only go back on one way for the bolt holes to line up, and there is a flat spot that everything lines up at. Should take a few minutes if the d-shaft is already removed.

a super thin coating of sealer is not going to hurt anything, I have done it several times in the past, no issues, just don't go gobbing it in there, just enough to basically coat the metal and create a seal.

Sounds basic! Someone told me they where a bitch to get out but I wasn't sure! Thanks for all the help guys!!!!

sorry Brian, I was thinking pinion seal....the pinion support as mentioned above should come out rather easily with the 6 bolts removed...be sure to clean the area real good prior to taking it out, then keep track of the shims (they only go on one way) then just smear a finger on each of them for sealer. Bolt it back up.

Lol my bad for the confusion I didn't mean you I was referring to a friend who told me to beat the **** out of it with a hammer! May be my favorite technique but one I like to use as little as possable! I got what you meant and it was helpfully so thanks for your time
