I have a 2005 F250 4x4 and I need the torque settings for the various bolts on the rear. I need torque values for the following parts:

4 Backing plate retainer bolts
2 Caliper bracket retainer bolts
2 Caliper slide bolts
8 Axle retaining bolts

Thanks,
Ron

 

i just did backing plates and i didnt and dont ever properly torque the bolts. the only one i torque properly are the spindle nuts that hold each hub on. i just get em really tight. lol but here ya go.

Torque Specifications Rear
Description (lb/ft)
Disc brake caliper pin bolts — Excursion, F-250/F-350 with Ford and Dana axle = 27
Bleeder screw — Excursion, F-250/F-350 with Ford axle = 8
Rear wheel disc brake adapter bolts — Excursion, F-250/F-350 with Ford axle = 150
Rotor shield bolts — Excursion, F-250/F-350 with Ford axle = 8
Rotor-to-hub bolts = 94
Disc brake caliper anchor bolts = 128 lb/ft
Stone shield nuts = 46

 

Thanks for the numbers. Do you have the values for the 8 axle retainer bolts which hold the axle to the hub?

 

heres a great write up

sorry cant find the sceps. i just used my built in torque wrench.

 

I have one of those built-in torque wrenches too but as I age, I have noticed that it is getting weaker!

Do you have any hints about the new style hub retaining nut? I had an 1967 truck which used 2 locknuts to hold the hub in place. The nuts were straightforward to tighten.

Then I had a 1984 truck which used a single locknut that had a nylon insert. The nut was tightened and then a key was driven into the nylon insert to hold the nut in place.

This 2005 truck has a multipart locknut which appearently contains a locking mechanism of some sort. Do I need to do anything with it other than use the locknut tool to tighten it? Do I need to put inward pressure on the tool to disengage the locking mechanism?

Thanks.

 

Not sure where joe_r_dog acquired his torque values from, but they are not accurate for a '05...

4 Backing plate retainer bolts - 101 lb/ft (137 Nm)
2 Caliper bracket retainer bolts - 203 lb/ft (275 Nm)
2 Caliper slide bolts - 26 lb/ft (35 Nm)
8 Axle retaining bolts - 80 lb/ft (109 Nm)

As for the hub nut, nothing really special there. Just tighten to 60 lb/ft (81 Nm) while rotating the hub occasionally, then adjust as follows.

New Bearings - Ratchet back 5 teeth/notches (1/8 turn) on the hub nut.
Used Bearings - Ratchet back 7 teeth/notches (1/6 turn) on the hub nut.

 

Thanks, PowerStrokeHD. Last night, I picked up a Haynes manual and your values correspond to those numbers which also match up with torque values I found in another thread here. Now I feel like I have the correct values.

I want to make sure I have the terminology right too because I am replacing the rear backing plate assemblies which have rusted out ( this should be a whole other rant thread). Are my below descriptions correct?

Backing plate retainer bolts - these are the 4 nuts which mount the backing plate assembly to the axle housing.

Caliper bracket retainer bolts - these are the 2 bolts which fasten the caliper mounting bracket to the bracket which is part of the backing plate assembly.

Thanks for the help.

 

Close enough on the terminology...

Backing plate retainer bolts aka Brake Caliper Support Bracket Bolts.

Caliper bracket retainer bolts aka Brake Caliper Anchor Plate Bolts.
