why is the end of my birf sticking out?

[photomike]

Just got my truck in Nov, and found my bearing cap popped off and grease shooting all over my front Right rim this AM.

Had the Birf looked at by IPOR in Nov.on my way out of town as they had just done a replacement for the PO and same problem then, grease leaking out of the endcap.

My mech here in Dallas cant look at it until Thursday. What is the normal cause of this? I'm new to LC's but not Toy's, just dont know much about Birfs. cant even fit the end cap back on.....

Either you have the incorrect and longer birf that shouldn't be in a 93 or your c clip conecting the birf to the inner axle has broken allowing it to move outward.

 

[photomike]

Ah, but if it was on and good from then to now, could I assume that the Birf is the right length and the c-clip has just given way?

Thx for the quick reply.

Well I should have asked if it was the original birfs, are they?

If they are then you can rule out the wrong sized one. still possible for the c clip to have broken but not likely. Most of the time it is people not reinstalling new ones when they switch the sides on them that can cause that.

You have a new long birf with an old short drive flange.


Outward birf movement is controlled by the spindle bushing, not the snapring.

Short ABS birfs have been superceeded to the longer version by Toyota. It is a multiple substitution which requires repalcing the drive flange as well.

the birf floats in the spindle. What keeps it in position is the clip on the outside and the birf contacting the brass bushing in the spindle on the inside.

So if the birf is sticking out too far you either have the wrong drive flange for the birf installed or the brass bushing has issues.

EDIT: I see Dan covered this while I was reading and responding.

Here's the difference:

Shot a note to them and they remembered me and the truck. asked me to send over some pics as well.

How do I approach it from here especially since I am a long ways away.... :/

If the bushing was worn that badly it wouldn't be there.....

 

[photomike]

ooh ok. Looks to be a little bit intensive to say the least.

 

[photomike]

So do I need a short/short? or a long/long?

You need a long drive flange.


Look at the other side and see if it is oriented properly.

well, not all of it anyway.

 

[cruiserdan]

well, not all of it anyway.

The thrust wall of the busing is thinner than the difference in the two birfield heights. To get it to stick out that far the birf would have to wear into the back face of the spindle (after it wiped-out the bushing) at least ~3mm.


Have you got the exhaust plumbed yet?

 

[photomike]

I'll update once I hear back from them. You guys astound me with your fast knowledge. Thank you!!!

You are in good hands between Cruiserdan and Landtank. When I bought my cruiser (93) I had to purchase a new drive flange because of the same issue. American Toyota hooked me up.

Im surprised that the grease is that thin and it made it out to the end after a recent replacement/repair. My guess is there is more going on then a long birf or a bad brass bushing.

Pop one of your dust caps off and hop on the freeway.


It doesn't take very long.

Phil doesn't have dust caps.

He's got Aisins.
