Question about 2002 Ford F150 Regular Cab

5 Answers

Rear wheel axel Ford F150 2002 how do I dismantel it to check if it is a bearing, making a clunk sond , parked as it has gotten, worse. I have very little money and I would like to fix it myself. I have a 2000 F150 that is making the thump noise also. I have put the Truck on jacks and checked the drive shaft UJ. There is no movement in either joint. As I turn one of the rear tires I feel slack and notice the thump. Could this be the pinnion pin being broke or moving out some how. It only started this a couple of weeks ago.

Hi and welcome to FixYa,

May I offer an alternate/additional possibility you may want to consider/check:

  • pinion yoke - that would be where the rear universal (U-joint) is attached to;
  • pinion nut - could have backed off.
Good luck and Thank you for using FixYa.

It sounds more like a u joint than a bad axle but i could be wrong you should check the u joints first and see if there is any play in them

If it were a wheel bearing problem, when you have the wheel in the air and hold the top and bottom or left and right, you would be able to move the wheel a little and possibly hear the clunk. Since you are hearing it as you rotate the tire this indicates a problem with the differential. You could take the cover off the pumpkin and have a look, but it isn't something easily fixable. It may be as involved as removing both axles and removing the differential, not an easy thing for a backyard mechanic.

My differential on my ford falcon au series 2 is making a grinding noise at a certain rotation, there is plenty of oil so it maybe the axels, i have it up on stands and when its running the hubs look like...


Check the wheel bearings, if its not the wheel bearings then its your axles. A grinding noise would be a sign of bad wheel bearings. If the rear end is off the ground grab the top and bottom of the tire. Can you wiggle it REALLY good? If so bad wheel bearings.

Rear wheel bearing


if its like the 99 winstar:

safely support the van, remove rear wheel, remove brake drum, remove grease cap. remove caged locknut assembly (38mm socket i think.) then pull the hub assembly from the axel. you may need to cut away the inner race if the bearing falls apart. clean axel, apply alittle anti size compound, then push on the new hub assembly. tighten down the hub nut to specifications (should be on the leaflet in the new bearing package), install dust cap, install drum, install wheel, lower and drive :)

2wd front wheel need to replace bearings or hub assembly which is best


A Front Wheel Drive Vehicle Can Have Two Types Of Rear Wheel Bearings: Serviceable Bearings, Or Nonserviceable, Sealed Bearings. When Sealed Bearings Fail, The Bolts Holding The Bearing And Hub To The Axel Or Control Arm Must Be Removed. When Installing The New Bearing Assembly, Torque The Bolts To Specifications.Some Manufacturers require The Use Of New Fasteners When Rear Bearings And Hubs Are Replaced.

When A Serviceable Wheel Bearing Is Used, The Bearing Can Be Disassembled And Packed With Grease.It Is Serviced Like A Front Wheel Bearing On A Rear-wheel-Drive-Car.

2001 and 2002 jeep grand cherokee. while making hard left hand turn experience rumbling sound doesnt happen when driving straight or right turns. Cant decide if sound is from front or rear area


Try checking the bearing in the left wheel if the rumbling is on the left side. Sometimes bearings can be worn down and sometimes may even twist or bend.

When i put my car in drive the rear right wheel makes a scrubbin


i had the same problem and i ended up changing the rear wheel bearings and axels, look under the car near the rear wheel seals, if they are leaking the axels are going to be worn also and need replacing.

How do I change axel bearings on jeep GC ltd. 5.9? Need a step by step for this procedure. My right rear makes noise when I turn the wheel all the way to the right and go in reverse, almost like a binding...


Job is not terribly difficult, but instructions are too long to re-write them. Get yourself a haynes manual (about 20 bucks) and it will guide you through the job. If you need any help along the way, I'll be glad to help! (manual will help with lots of other stuff as well!!
If you have the setup I'm thinking of, make sure you buy a new diff cover gasket and gear lube along with axle bearing.
good luck

Rear Axle Bearing


i know for a fact that the bearing comes with the hub., and if the old bearing is badly damage you may need to heat it to remove it from the axel...so this may be a rather big job if your not equipt
with torch or other ...
