Wheel Bearing EXPLODED

[DangerRanger96]

Hey guys...just looking for the torque specs on the front 4x4 wheel bearings (manual hubs) on my 1996 Ranger. I've looked in my Haynes manual, but I find it hard to believe that ft/lb. I've also read in a TRS forum that 250 ft/lbs. NO WAY! I've been told conflicting info to this point. I really want to do it right the first time without trashing new bearings and races. I've looked in the tech library also, to no avail. I appreciate all the great ford guys on here and thank you in advance for the great advice. Thanks, Terry

For the outer wheel bearings, 250ft-lb's is a good number. I believe 150 was the original spec but isn't usually enough.

Not sure on the inner, but it's going to be more like a few inch pounds.

HOLY CRAP!!! SERIOUSLY?? 250 for the wheel bearings? Well, that makes 3 ppl saying 250. Just seems tooooooooooo tight on bearings.

Ok, I know I was the one asking the question here. But I just got off the phone with the local FORD dealer. The service dept. tell me that the inner retaining ring/washer is 35ft/lbs. Then the lock washer goes on. Then the outer ring/washer is 165ft/lbs. I really think 250 ft/lbs is way way TOO much. How would the bearing even spin? Any other input would be greatly appreciated. Thanks.

Eh?

On my 88 Ranger I just tighten the nut by hand (or a wrench) until the grease squirts out around it and it's flush...then I put that little cap thing on and put the cotter pin through it...I did my first wheel bearings on my first Ranger after having to replace the spindle due to the bearing going south...and after I did them I put on another 50,000 km or so and never had a problem with them...

Does that apply to only late model Rangers???

It applies to TTB 4x4s, not 2WDs.

There's no way the inner ring should be torqued to 35 ft-lb's (except maybe for the initial squeeze to get everything settled in before you back off?). The outer ring really doesn't do anything but hold the inner ring in place, that's why you can torque it so much. Too loose and it will start to back off, allowing the inner ring (where it really matters) to loosen.

Whew!

For a millisecond or two I was about to run out and twist my nuts till they bled...

 

[RustedRanger]

OUCH!!! ROFL!!! Not a nice mental image!

I have always just torqued the inner down to 35ft/lb and then backed it off 1/4 turn or so, then the outer nut as tight as I can get it. My 1/2 torque wrench only goes to 150 so somewhere around that.

Tighten the inner nut and the inner nut ONLY to 35ft/lb and rotate the rotor several revolutions

Then back the nut off and retighten to 35INCH/lbs

Install the perforated washer and thread on the outer nut.

the OUTER nut get tightened as tight as you can make it
225-250ft/lb IS entirely reasonable.

That OUTER nut isn't tightening the bearing
it's only squeezing the washer agaisnt the inner nut and LOCKING
the two nuts and the washer together.

The inner nut is the "adjustment" nut
the outer nut is a "jam" nut

My "big" torque wrench is 36" long and 3/4 drive and
225ft/lb isn't even half scale on it

But oddly the scale is marked in inch pounds

it's strange to torque something to 7200in/lbs

Here's what Alldata says about it:
Loosen inner wheel bearing locknut using a suitable spanner wrench, then torque locknut to 35 ft lb .
Loosen inner locknut 1/4 turn, retighten to 16 inch lbs ., then install lockwasher on spindle. If necessary, rotate locknut slightly to align pin with closest hole in lockwasher

Allan, the inner only goes to 16 in/lbs, not 35...
