Re: how do i lube my ballbearing joints in my 94-...
I think you mean 'ball-joints,' part of the steering and suspension.
Most modern vehicles, with some exceptions, no longer have the Zerk fittings once found on each ball-joint, but 'lifetime' lubrication packed into the joint and decently sealed to prevent loss of grease and incursion of dirt and moisture.
You may have sealed ball or roller bearings used in your wheels since the cone-type, adjustable bearings are also less common than they once were.
In my experience, these sealed assemblies have become ever more reliable as materials and manufacturing techniques have steadily improved.
Many such assemblies now really do last the usable life of our vehicles.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

they are pre greased, no nipples. When I replace the ball joints, i drill a hole, and put my own grease nipple in. That is the diff. between the long warranted ones, and the economy ones, a lousy grease nipple. you may need replacement
You need a grease gun and a tube of grease for your particular vehicle make. You can purchase both at any auto parts store. If you haven't replaced the ball joints since the vehicle was made then you probably wont be able to grease them. Most vehicles come off the line without access. However aftermarket parts have points where you can grease. Take your grease gun and stick the end over the nipple,(sorry can't think of the name for the **** things that you grease into, so Im calling them nipples.) Anyway, pump the gun until grease comes out from the joint and that should do it. Really pretty simple operation provided you have the nipples at the joints already. Hope this helps.
Okay, if we're talking about a chev 1/2 ton, you have to grease the ball joints, upper and lower. To get the top one you'll probably have to turn the wheel to the left or right all the way, and you will see it on top of the ball joint. The lower ones will either be under the ball joint or sticking sideways. Other than that you have tie rod ends, and you maybe found them already. There may or may not be grease nipples on your u-joints on the drive shaft. Originals are usually sealed, and replacement have nipples. Good luck. Hope this hepls.
If by lube nipples you mean grease fittings, which is where you grease the ball joint and the a arms etc. Most new autos including Acuras don't have them. In order to grease them they do make a grease gun end that is a hollow needle that can be inserted into the rubber part between the joints. I hope this helps.
If you have 5/16 plugs in the front end parts you can replace them with standard zirk fittings and lube them...many do not and the only way to service them is when they fail, new parts will have a provision for a fitting.
you do not lube them they are full of grease.if boot tears and splatters the grease out then you replace boot or anymore just as cheap to replace axle. Some lube centers try and sell a lube service on these where they poke a hole in your boot and pump grease in them.This is a no no as it causes your joint to start leaking
