Front Wheel Hub Loose

92 4.0 5spd..........discovered my PS front wheel hub very loose. taking it apart am stuck in need of a 1 3/8" socket to get the big nut off. can you all confirm is in fact 1 3/8" the correct socket i need. once i get it all apart any idea what will need replacing? i don't think there are bearings in there? have my chilton book to go by. something in there is very worn, wiggles a good '1/4" ' amount.

Those unit bearings are sealed & non-serviceable.

Actually the nut is 36 mm.
You'll need to replace the entire unit bearing assembly.
Buy good ones such as Timkens. I'd suggest you replace both as the other is probably not too far behind.
You'll also need a 13mm 12 point socket to remove the 3 bolts holding the unit bearing(s) in the knuckle.

yup. What joe said.

You need a 36mm socket, then a 1/2 or 13mm 12point socket to get the unit bearing off the knuckle.

Easy job, unless you have a lot of rust. As I recall the part is about $75


I would probaby replace the brake pads while it's all apart

And be careful not to pull the axles out with the hib assemblies its very easy to damage the seals putting them back in

Officially I have to agree with Joe.

Unofficially I disagree. I have had them separate while knocking them loose for axle rebuilds. I repacked with new grease then tightened them up. I have a pile of old ones and didn't expect it to last. It actually has lasted very well.

So you can take that for what it's worth. It will be obvious if it is shot or in need of a cleaning and new grease. Those bearing will be shiny and smooth or corroded. (they are the size of dimes)

Went to Lowes bought a 36mm socket and got it apart. Napa where i live (Maui) wants $144 for one hub unit, i found it for $45 on the internet with free shipping. Of course no free shipping to Hawaii so i ordered 2 and shipped them to a friend on the mainland and they will ship to me for $15. USPS flat rate. I am shut down for now until i get the parts.
thanks for all the input..........

great tip, would have never thought about that. i put a big screwdriver thru the outer yoke keeping the axle from coming out.
