In the wrong forum I posted about my Differencial
The purpose of which was to identify the correct one
in order to purchase the correct bearings
I have posted a picture of the right side axel
No scratches or pits so is it ok to put in back in with new bearings
Count the bolts on the backside of the chunk (the one you removed to take the c clip out to get the axle out) if it is 10 bolts that holds that cover on it is an 8.8 rear-end.
Now if it is 12 bolts it is a 9.75 rear-end 5 bolt lug pattern.
Note: ( a 10.25 has 12 bolts as well, but not 5 bolt lugs nuts that I have seen in your year)
Or you can look at the tag on the rear-end and go by that number if the rear-end is the one that came in the truck or the Vin number or the axle code on the door post.
You have a 28 or ( 31 spline axle truck rear-ends 8.8 or 9.75) if someone has changed the rear-end and taken one out of a car more than likely it is a 28 spline axle unless it came from a Mustang Boss or Shelby then it would be a 31 spline 8.8. So count the splines on the end that goes into the chunk and see if it is a 28 or 31 spline if you want to know which spline you have.
So I got the wheel bearing replaced, only to find out the rear u joint was also bad
I took it to a repair shop, there telling me there is like 18 different u Joints for that truck
and they cant seem to find the correct part after they tore the old one out
I told them to take it to the dealer and compare it, they got all pissy
I think there full of BS
How do I tell which is the correct part
What year truck, transmission, and is it an 8.8 rear-end or 9.75?
4x4 or rear-wheel drive (means two-wheel drive ) and what engine size, 4.2. 4.6 or 5.4. These are the questions that a parts store will ask you and your answer is the correct u joint size. Most u joints will fit a lot of different cars and trucks and will cross over to different makes as well.
U-joint listings are a PITA - anymore I yank the old one and measure cap OD and distance across caps or snap ring grooves. If that's not possible I still get under there and at least measure cap OD, ballpark distance/OAL and note snap ring style(s)...ie like the Dodge 811X uses internal snap rings on 2 and external on the other 2 so if given a multiple choice selection that narrows it down pretty well right off the bat.
