Awhile ago my mechanic told me that my front right axle boot was leaking grease. Well, today it began to make noise. Grinding squealing. What needs to be replaced? CV joint, CV axle or entire drive axle?
On this type of vehichle, you have two axles in the front; one going to each side. Chances are that the boot at the axle joint was torn and that is why you are having problem. In teh past people used to replace the boot, this day and age its actually cheaper to replace the axle. So you would need to replace that side of the axle (the half shaft).
Well this means that your cv-joint boot has been cut or split and has let dirt in and greas out,if it is clicking,or sound like your rolling a jar of marbles you will need to have it repaired or get a rebuilt cv shaft.but yes you can just have the cv-joint repaired

the CV joint of the axle most likely at the hub end of axle.contained inside of a rubber boot full of grease.you cant see the actual joint but by graspping the axle and asserting force up/down,left/right you should be able to tell if the joint has "ruptured" or seperated. best fix is ALWAYS a new axle.repairing a boot or joint = $$parts,$$$$labor?
/new axle=$$parts,$labor plus most new after-market axles carry a lifetime warranty and its only a matter of time until the boots dry rot loose grease and go bad.next time only cost labor to switch axle.A "slipping" axle will give a loss of propellsion will actually prevent the transfer of driveline power from transmission to wheels.
Grinding noise upon turning is normally one of two issues. First, and most often, it is caused by a worn out outer CV joint. If your vehicle has more than 50000 miles on it and the axle shafts have never been replaced, this is what I would suspect first. In addition, CV noise will be louder when turning under power (gas pedal pressed) than when coasting into a turn. The other possibility is a front wheel bearing assembly. These are not as common, but do wear out as well. The wheel bearings will usually make no noise when going straight, but will make noise upon even the slightest side to side turn. CVs on the other hand, usually grind only when going into corners or making left or right turns. If you suspect a CV joint, but don't have high mileage, you could have a torn CV boot that resulted in the grease that lubricates the joint being depleted and causing the noise. You can inspect the out boots visually for tears....grease leaking out usually leaves telltale spatters in the wheel wells also. Replacement of the CV joint can be done, but it is usually cheaper to replace the entire axle shaft as they are serviced as a unit.
Most commonly, that sound would be coming from your brakes. Have you had them checked or replaced recently?
Brakes will squeal if they get worn down too far and require brake pad replacement. Sometimes they will squeal in perfectly harmless condition such as when they get wet, which should clear up quickly as they dry, or if they experience too much vibration. New brake will also sometimes come with either gaskets, metal clips, or a sort of anti-vibration grease or putty to reduce squealing from harmless vibration.
In any case, I would recomend having somebody knowledgable (or service center) check the brake pads for wear and replace if neccessary.
On more rare occassions, the squealing could be coming from other sources such as being in need of chassis lubrication, axle grease, and so forth. Most more serious mechanical wear or failure would sound more like a grinding noise.
You have to replace the worn axle assy on that side No way to grease it- unless you remove the axle & dissassemble it & wash it clean first Surely a load grinding noise tells you the problem is well beyond any greasing. You can only remove the axle,wash it out & grease it, if the boot rips & you get it apart in a day or so,otherwise road grit will destroy the axle before you know you have an open joint from a boot issue On a 1998-- I would do both sides & be done with the axles
CV? ever do a CV check, FWD has CV axles, and do not last forever. nor for life of engine. about 300k miles. service them. or get rebuilts. better yet , pay for diagnosis, as cars this old all have , more failures. some are dangerous to you , family and others on the road.
This noise is caused by a worn or damaged front drive axle Constant Velocity Joint (CV for short), there is one of them at each front wheel just behind the brake disk on the end of the drive axle, they have a rubber cone shaped grease boot over the joint, check to see if the grease boot is torn, the joint then runs dry of grease and makes noise, at that point it must be replaced. Have a shop put in the air and inspect them both.
It could be caused by a torn CV joint boot on the axle. The boot holds grease to lubricate the CV, and when the boot is torn, the grease comes out, causing a click or grind. I;m assuming this issue is not brake related of course.
CV Joint went out. since it gets worse when you turn right it is most likely an inside drivers side CV joint or the out side passenger side. The popping sounds was probably the dust boot popping from pressure build up which should make it simple to locate since you just need to identify the boot with a tear in it.
