By learning 3 figure bearings and coordinate geometry in case you come into difficulty you'll be able to tell rescuers where you actually are by giving them your actual coordinates.
I am assuming that you have a 4X4 and are talking about the front hubs. In which case, they are a sealed unit with the ABS sensor integrated and they come as a package. They can not be greased or serviced. The only real part that can be serviced is the needle bearings on the actual hub assembly, but that should not really be necessary. I re greased mine when I changed the bearings. tdwills@atlanticbb.net
1.put the wheel half way were you put the wheel on the skateboard then push the front of the wheel down and the back of the wheel up and one will come off .do the same with the other if they don't come of put wd40 on them and let them rest a while and do the steps again. if you have any questions go to youtube.com
If you have replaced all this it may not be a belt. It may be your alternator itself. These have bearings inside them and they do wear out. The only way to check is to remove the belt and spin the alternator to see if that is what is noisy. It may wobble if the bearings are bad. It should turn smoothly if not.
Defective oil pressure sending unit? Excessive engine wear (bearings)? weak oil pump? Try installing a manual gauge to determine actual oil pressure
Check oil level Check actual oil pressure with a mechanical gauge Could be caused by excessive engine wear (bearings) or weak oil pump Bad oil pressure sending unit
My advice to you would be a recommendation to see if an ASE instructor at your local community college can work with you on this, because replacing races and bearings. The short answer is that you'll take off the wheel, and take off the hub... then you'll remove the bearings, punch out the races with a hammer and race punch, and reinstall the new races... you can grind down the old races to use as drivers for installing the new ones, or use actual race drivers. It's very easy to get this wrong if you don't know what you're doing.
Being a former U.S.Marine,I can say that we reffered to this type of action and men as a armed boarding party.
1. Defective switch 2. Short in wiring 3. Worn oil pump 4. Worn bearings Hook a direct reading guage to the place where the switch screws in to see what the actual pressure is. If the pressure is good, look for electrical trouble.
If disk brakes the rotor could be worn and either needs replaced or turned.(put on a lathe to put it back in true again)Other possibilities are worn wheel bearings or worn ball joints. Best to have a shop look at it to determine the actual cause. My car does this when there is a tire out of round.
Most certainly but a thump as described sounds more like one or more of the front shocks has gone south and lost its ability to dampen a bump. The thump you might be hearing is the effect of the shock actually bottoming out on its stroke and what you have as a result is hard contact with the components. I would look into the bearings for proper pre-load and also the shocks plus any ball joints, tie rod ends and other steering components. Many rack and pinion racks become loose as the result of worn dampening bushings that hold the actual rack to the vehicle frame; I would look into that also.
Low oil pressure due to excessive engine wear (bearings) Defective oil pressure sending unit? Try a manual gauge to determine actual engine oil pressure Try a heavier engine oil i.e. 20W-50
