4-WD 1 ton front and rear bearings

[NDearyan]

I have my 1993 1 ton 4-wd all up on blocks. :{ It started out as ONLY replace the emergency brake cables. NOW it is new brakes all around, and turn the rotors and drums. I have replaced all the seals, and repacked the bearings.



Now, my question: I have everything cleaned up, and I'm installing the FRONT ROTORS, and ALL I have is a Hayes book. :{



I THINK my front end is a Model 44 or 60. It has lockouts, and 6 hex heads come off first.



According to this book you tighten the spindle nuts to 50 LBS. Then back off, and retighten to 30 LBS. THEN you back them off 135°-150°. IS this right?



I've NEVER seen one that gets backed off like this!



Please help, as I have to get it back on the road YESTERDAY!





I posted this at "911", but I suspect that the 911 forum is visited by more new owners than 1 gen types!



And, I am doing the REAR ones too! According to this book, tighten until the wheel starts to turn just a little hard, then back off a little. Is this right?



Thanks a bunch!

Howdy, Hope I can help.



Your Front axle would be a Dana 60.



Factory Manual says that on the rear, Tighten nut to 120-140 ft-lbs, while rotating the wheel. Then loosen 1/3 of a turn, and install lock.



You got the front right, then tighten outer locknut to 65 ft-lbs.



Good Luck

Yea, been there done that.



The theory behind "why" is that you are seating the bearings/races and taking all the play out of the bearings and the grease in the interstitial spaces.....



Interstitial is one of those cool medical words that I heard on E. R. once... ...

ON THE FRONT:



When I do what I wrote above, the hub actually has SLACK in it.



It BOTHERS me to leave slack in it!



It just does not seem right.

If there is slack in the hub its too loose. I usually back off a max of 90 degrees after tightening to around 120 ft/lbs while spinning the hub. Setting by feel is not very scientific but haven't had one come apart yet.

I have always done the front bearings as cerberusiam has described... . I would describe it as backing off just a scoosh until I feel just a little play without getting a clunk when I shake or rock it.



I guess that means the interstitial spaces are non existant.





But I prefer to use precise engineering terms like "no clunk", "a little play" and "just a scoosh". :-laf

Hopefully this helps.

You will also hear interstitial if you attend a class on underground storage tanks, yawn . As far as the bearings go, I've never set any wheel bearing by torque. I tighten it good to get the slack out, back off the nut until just loose and then tighten maybe an 1/8 of a turn after the nut touches the washer. Haven't lost one yet.

I'm really getting connected to "Cerberusium" 's method above. Using the prescribed (By the book) method above seems TOO TIGHT on the rear.
