The boot just inside the brale disk is throwing grease all over the under carriage. Is this the CV joint?

Once there clicking, it needs to be replaced... It's your half shaft..

CV joints may be going bad, could be the left or right, never heard of both sides going @ same time, but who knows until they get checked. Inspect the BOOTS, for torn conditions allowing grease to come out, that one would be the suspect bad cv joint, will get worst , the retainer band may have come off on outside joint throwing grease out, needs replaced, call for parts cost for the complete cv joint, one side. otherside may be ok, but be prepared in case it needs replaced also !

If you clean away the grease inside the boot and look where the axle goes into the joint there is a snap ring there. Spread the snap ring and pull the joint off the axle.

I would replace the complete axle assembly,
it would be cheaper and come with a warranty.

Instructions

1. Remove the CV Joint
   • Remove the boot straps from the CV joint using a standard screwdriver or a pair of diagonal cutting pliers.
   • Slide the boot back over the interconnecting shaft.

     Detach the stop ring at the base of the CV joint assembly using a pair of snap ring pliers.
     

   • Pull the CV joint assembly from the interconnecting shaft to force the snap ring at the top of the shaft through the CV joint assembly.
   • Tilt the inner cage (the cage holding the balls in place inside the housing) in different angles to remove the six balls. Use your thumb or a hammer and a wooden dowel, if necessary.
   • Tilt the inner cage enough to remove it from its housing.
   • Rotate the race inside the cage--the part that holds the balls against the inner cage--and remove the race from the cage.
     Replace the CV Joint
     • Apply a thick coat of grease to the new CV joint race using special high temperature/high pressure grease (see Tips below).
     • Install the race inside the new cage. Then install the cage/race assembly inside the CV joint housing.
     • Tilt the cage at different angles and fit the new balls in place.
     • Slide a new CV joint rubber boot over the interconnecting shaft.
     • Install a new snap and stop ring on the interconnecting shaft.
     • Push the interconnecting shaft through the CV joint assembly to force the snap ring through the assembly.
     • Apply a thick coat of CV joint grease to all moving parts of the assembly.
     • Apply a coat of CV joint grease to the inside of the rubber boot. Then slide the boot over the CV joint assembly.
     • Install the boot straps at each end of the boot, and tighten the straps using a clamp tool or screwdriver, depending on the type of clamp.
     
     
     

1. bad tire
2. bad rotor
3. bad axle

check tire first . not cv boot it just a cover for the axle - hold grease - dont let dirt in axle nuckles.under cv boot is the axle joint if boot is torn it lets grease out an dirt in an drys the joint out causing problems....

CV-Joints
Overhaul
These vehicles use several different types of joints. Engine size, transaxle
type, whether the joint is an inboard or outboard joint, even which side of the
vehicle is being serviced could make a difference in joint type. Be sure to
properly identify the joint before attempting joint or boot replacement. Look
for identification numbers at the large end of the boots and/or on the end of
the metal retainer bands.

The 3 types of joints used are the Birfield Joint, (B.J.), the Tripod Joint
(T.J.) and the Double Offset Joint (D.O.J.).

NOTE: Do not disassemble a Birfield joint. Service with a new joint or
clean and repack using a new boot kit.

The distance between the large and small boot bands is important and should
be checked prior to and after boot service. This is so the boot will not be
installed either too loose or too tight, which could cause early wear and
cracking, allowing the grease to get out and water and dirt in, leading to early
joint failure.

NOTE: The driveshaft joints use special grease; do not add any grease
other than that supplied with the kit.

Double Offset Joint
To Remove:

NOTE: The Double Offset Joint (D.O.J.) is bigger than other joints
and, in these applications, is normally used as an inboard joint.

1. Remove the halfshaft from the vehicle.
   
2. Side cutter pliers can be used to cut the metal retaining bands. Remove the
   boot from the joint outer race.
   
3. Locate and remove the large circlip at the base of the joint. Remove the
   outer race (the body of the joint).
   
4. Remove the small snap ring and take off the inner race, cage and balls as an
   assembly. Clean the inner race, cage and balls without disassembling.
   
5. If the boot is to be reused, wipe the grease from the splines and wrap the
   splines in vinyl tape before sliding the boot from the shaft.
   
6. Remove the inner (D.O.J.) boot from the shaft. If the outer (B.J.) boot is
   to be replaced, remove the boot retainer rings and slide the boot down and off
   of the shaft at this time.

To Install:

NOTE: Be sure to tape the shaft splines before installing the boots.
Fill the inside of the boot with the specified grease. Often the grease supplied
in the replacement parts kit is meant to be divided in half, with half being
used to lubricate the joint and half being used inside the boot.

1. Install the cage onto the halfshaft so the small diameter side of the cage
   is installed first. With a brass drift pin, tap lightly and evenly around the
   inner race to install the race until it comes into contact with the rib of the
   shaft. Apply the specified grease to the inner race and cage and fit them
   together. Insert the balls into the cage.
   
2. Install the outer race (the body of the joint) after filling with the
   specified grease. The outer race should be filled with this grease.
   
3. Tighten the boot bands securely. Make sure the distance between the boot
   bands is correct.
   
4. Install the halfshaft to the vehicle.

Except Double Offset Joint
To Remove:

1. Disconnect the negative battery cable. Remove the halfshaft.
   
2. Use side cutter pliers to remove the metal retaining bands from the boot(s)
   that will be removed. Slide the boot from the T.J. case.
   
3. Remove the snap ring and the tripod joint spider assembly from the
   halfshaft. Do not disassemble the spider and use care in handling.
   
4. If the boot is be reused, wrap vinyl tape around the spline part of the
   shaft so the boot(s) will not be damaged when removed. Remove the dynamic
   damper, if used, and the boots from the shaft.

To Install:

1. Double check that the correct replacement parts are being installed. Wrap
   vinyl tape around the splines to protect the boot and install the boots and
   damper, if used, in the correct order.
   
2. Install the joint spider assembly to the shaft and install the snap ring.
   
3. Fill the inside of the boot with the specified grease. Often the grease
   supplied in the replacement parts kit is meant to be divided in half, with half
   being used to lubricate the joint and half being used inside the boot. Keep
   grease off the rubber part of the dynamic damper (if used).
   
4. Secure the boot bands with the halfshaft in a horizontal position. Make sure
   distance between boot bands is correct.
   
5. Install the halfshaft to the vehicle and reconnect the negative battery
   cable.

Broken/Bad CV boot? Check the boot for cracks/tears/etc.

Good luck, TD

My L series throws grease up onto the exhaust pipes causing the smell, so you could have split boots on your CV joints. That could account for the smell. The noise could be coming from a rear brake, something in drum like an auto adjuster come adrift If you do have damaged CV joint boots, you will need to have them replaced immediately or you will wear these joints out very quickly.

Easy enough job really, jack car up, put axel stand under. remove wheel - remove hub nut, remove pinch bolt - prise open the pinch bolt part (sorry cant rem name) pop out the hub from the lower arm. Remove CV join from drive shaft. Usually a tap will pop it out.. sometimes theres a circlip that need removing (models vary). Grease up new CV joint - put grease in new boot, pop boot over drive shaft. put cv join on (replace circlip if provided in kit). join cv to hub - attach CV boot fully. fasten hub nut, replace wheel.

done. might need tracking again or aligning once you do this.

Does the pitch and frequency of the "noise" increase as you driving faster?

Check both tires for nails or rock stuck on the groves of the tires.

Check the CV joint.

The boot which make of plastic can come apart over time. If you see CV grease all over the under carriage of the care then you will need new boots or replace CV joints.

Inner and outer wheel bearings can also make noise when they are about to fail.

Check you service record for more information.
