Q:f-250 changing front wheel bearings?
Well, what's the problem? Do you need to know how to do it? How much it cost? What are wheel bearings? You have tapered bearings. When they go bad you change the inner and outer bearing plus wheel grease seals then get them repacked. Sometimes you can just have them tightened and that fixes it
Q:99 Lexus ES300. When I drive the car its fine for like the first ten minutes but after that when I stop at lights and for traffic the oil pressure will drops when the RPMs go below 500 or so. I took it in and they told me to keep thicker oil and Lucas Stop Leak in it. They also told me the bearings on the Camshaft are loose and thats why I'm losing pressure. Anyone know how much this is to fix? Is it possible to fix on my own? I'm a novice at best with cars. Also why would the oil pressure drop since the bearings are going bad? Just trying to understand the problem a bit better. Thx
it has cam bearings but they would not have anything to do with the oil pressure ! you get the oil pressure from the oil pump and the rod and main bearings, not the cam bearings ! do you hear any knocking ? if the cam bearings were loose you would hear a noise !
Q:How much speed can the needle bearing of inner bore 17mm bear?
The needle bearings with an inner diameter of 17mm have various forms.1. needle roller and cage assembly2. press outer ring needle roller bearing3. solid needle roller bearingsPermissible rotation speed of needle and cage assemblies:Grease lubrication: 16000rpmOil lubrication: 26000rpmAllowable speed of needle roller bearing for stamping outer ring:Grease lubrication: 12000rpmOil lubrication: 19000rpmAllowable rotational speed of solid needle roller bearings:Grease lubrication: 13000rpmOil lubrication: 20000rpm
Q:It's an 81 ford mustang 2.3L everytime we run it. It melts the cam bearings. HELP
It sounds like the oil passages are stopped up or the bearings are put in upside down. the cam is probably whiped out along with the bearings. The webs that the bearings fit into should be a tight fit so they hold them in place or they will spin.
Q:I went to Les Schwab and got my car checked out after I heard a clicky noise. I told them to check the bearings. They did and said they needed replacing and were in bad shape. They called me and gave me a quote for $500. Is that too much for replacing the wheel bearings, hub and an alignment?

Is that too much for replacing the wheel bearings, hub and an alignment?
Q:How does it keep from flowing into the turbine itself?
The bearings are located outside the casing on either end of the shaft. There is an oil pump that circulates oil through the bearing. A seal on the shaft keeps the oil from flowing into the turbine casing.
