My CV boot ripped. Thus, I just opted to replace the entire passenger side CV halfshaft on my 3vz-e (89' PU 4X4).

The issue is that the remanufactured CV shaft does not look the same as the one I took off my car. The difference is that there is a little piece of metal on the big end of the CV shaft. However, the remanufactured does not have this "shield" on it.

This "shield" seems to mate with the HUB perfectly. However, since the remanufactured doesn't have this shield, it appears that WATER or DUST could enter into the HUB and could damage the wheel bearings.

Thus, what is the purpose of the "shield" on the end of the CV shaft that was found on the OEM axle (and seems to mate with the HUB)? Also, is this shield recommended or not?

Thanks in advance,

Do you have a picture of said "shield"? I am having a tough time picturing what you are talking about.

 

What I am trying to describe is the shield in between the RED markings i made to the halfshaft.

The remanufactured cv halfshaft does not have this.

 

You should be able to get that shield off your old one by lightly tapping around the outside with a hammer and punch. If it doesn't come off, take it back and show them how the part they sold you is wrong. Its not SUPER necessary, but like all parts, is there for a reason.

 

Thanks for your reply DeathCougar!

I've been having bad luck with the CV halfshaft.

1) Bought remanu from Kragen (didn't have the shield). Installed it anyways and found that there was fitment issues. It seemed like it was 3/16" too short. The washer at the end of the CV axle would go on but the lock washer right next to it wouldn't go on.

2) Went back to Kragen, instead I bought a brand new Cardone CV halfshaft (this had the shield). Installed it as well, but it was also 3/16" too short. Only washer fit just like #1 above.

(I was pissed off, so I went in and talked to Kragen management and they showed me their computer and the part number which matches up correctly for my 3vz-e. Got my money back nonetheless.)

3) Went to NAPA, picked up the CV halfshaft (didn't have the shield), and I also brought the HUB because I was not re-installing everything without fitting the washer plus lock. This remanufactured CV halfshaft from NAPA fit as they let me bring in the hub into the store and try the halfshaft onto my hub. I installed it and was able to put the washer and lock on!!

Well, I still have my OEM CV halfshaft, and I'm reluctant in returning the core unless I can find out if this "shield" is necessary or not?

I may just have my OEM CV halfshaft rebuilt if this shield is needed?

I really don't think a hammer and punch will do the job (but i might give it a hammer or two and see what happens). It just seems like it's built like that from OEM for ______?

 

THe CV is not too short - you don't have it in all the way. It frequently takes some .... ummm ... "persuasion" to get in there.

NOTE: while you have the CV axle out, be sure to grease the spindle bushing where the CV goes through the spindle!

 

Hi TC,

Thanks for your reply. Although, I beg to differ. The CV axle might've not been shorter, but there were subtle differences in the diameter of the CV axle that mates to the hub. Refer to the attached pic. I've highlighted this with the green rectangle marker. With this increased diameter, regardless of how much persuasion you apply there still won't be enough clearance. I didn't even bolt in those 6 bolts that bolt the CV axle up to the diff.

I do agree that it takes some persuasion! However, I took the entire HUB off the truck and greased those Kragen axles. Then I inserted the CV axle through the spindle. Believe it or not, the Kragen CV axles were not long enough. Even the Kragen MGR and employee agreed.

This is why I transported my hub with me to NAPA and verified that there was enough clearance for the washer and lock on the end of the CV axle before I purchased it.

Not sure if there are any differences in CV axle, but I do have a CANADIAN model pickup truck that was imported to the U.S.

The question remains, what is that shield at the end of the CV axle for??

 

I'm sure its a dust shield or something - I have been running for like 3 years without them ...
