Better way to fix bent gasket/ring on CV axle?

I was looking to score a cheap used CV axle from a totaled truck as a trail spare instead of buying a brand new OEM one for over $300. I managed to secure this one for $80. The boots, threads, and axle itself look fine. However, the gasket (correct term?) is bent. Can I just hammer/pry that back into place or should I send the axle in to get repaired somewhere? Attached are pictures.

 

That axle shield and seal are pretty messed up! Looks like someone was unhappy with it! lol. That is the end that goes into the spindle, so you need to be sure that everything seals correctly so that the wheel bearings do not get contaminated. This can be fixed, but will take some time. Using a pair of small needle nosed pliers you can carefully work the metal dust shield back into shape more resembling the rest of the dust shield. When you do that the rubber part of the seal should conform back to it's original position.

 

or you can use a flat head screw driver and pound it out and replace just that cover.

 

Did you get this bent metal shield resolved? I have a similar problem as you where I got a pair of CV axles from LKQ and the wrench monkeys that took them off beat them up and they didn't put them in a box with padding to protect them so between removal and shipping the shields bot beat up. Mine look like they could be salvaged if I can get the metal shields back in shape. How important is it to get the shield close to where it was? It looks like the most important part is the rubber seal part not being interfered with. Do you have any pictures showing how you straightened them back out, etc.?

 

If they're that bent, you should get replacements, Toyota P/N 90304A0001 (no aftermarket equivalent as far as I could find).

 

Seal - Toyota (90304-A0001) seems to be the seal on the back side of the wheel bearing not the metal
Outer CV Dust Shield. Is the Outer CV Dust Shield even available? I can't seem to find it.

I did find this thread talking about the topic I found this on eBay
CV dust shield (front axle, outer CV) x 2-Toyota- 4Runner, FJ, Tacoma, GX470/460
https://www.ebay.com/itm/294906626001

Does this part work in both places?

^The diagram is incorrect (at least for 2nd/3rd gen Taco). 90304A0001 is the seal on the CV axle. The listing even says it's included with the CV axle. I've personally bought and installed that P/N because RCV axles don't include that seal.

I noticed on this listing for CV axles

$168 2 Front CV Axles With Outer Joint Hub Seals Compatible With 4WD FJ Cruiser; 2005-2020 4WD Tacoma; 2003-2018 4WD 4Runner; GX460, GX470

https://www.amazon.com/Cruiser-2005-2017-Tacoma-2003-2017-Runner/dp/B07N9KBJMX/ that it shows that it includes inner and outer seals.

The part I don't see is this large O-Ring. Does anyone know the part number for that and where it goes? It kind of looks like it might go on the 710573 Wheel Seal in the above.

 

^710477 goes between the hub and bearing. 710573 goes on the back of the spindle.

The O-ring goes between the bearing and the spindle. It doesn't have an aftermarket equivalent P/N. (Like the CV joint seal, it's obviously offered in the aftermarket as part of kits, but no one lists it individually.)

What about the big O-Ring they show? Is that something we also need?

 

Depends on the job. If you're only replacing the CV axle, the wheel bearing doesn't have to be separated from the spindle, therefore the O-ring is not disturbed. If you're replacing the wheel bearing due to wearout, the O-ring should be replaced. Toyota's O-ring P/N is 9030192003. Some aftermarket hub-bearing assemblies, for example Moog 515201, comes with a replacement O-ring.

 

Are these parts equivalent parts or is the 710477 used somewhere else and if so where? It is included in that CV axle kit. It is a little confusing as to where they intend for the 710477 part to be installed.

710477 goes between the hub and bearing. Unless you're separating the hub from the bearing with a hydraulic press, that seal doesn't apply.

BTW that O-ring is available from SKF under P/N 30192.

 

Thanks!!!
That is what I was starting to sort out from looking at the diagrams. Some sites diagrams are better than others.

 

Is there any aftermarket parts to substitute for these?

I am building a source list of all of the parts required to do a full CV axle rebuild. I think I have everything except for the CV Boots, grease, clamps kit. What are good cost effective but still quality sources. What options are there for small lifts like 2" to 2.5" and also for higher lift options on boots?

 

No aftermarket P/N I'm aware of for 90304-A0001.

The dust cover on the inboard side is a small sheetmetal shield. It doesn't contact anything in normal use and typically doesn't need to be replaced.

For boots just use the Moog or Beck Arnly kits on Rock Auto. If you stretch the inner boot a little and cinch it down with a hose clamp, it will accommodate higher lift angles.
