Knocking B4

[ReubenH]

Hey. Have been looking at a tiptronic B4 RSK with reported knocking. We initially suspected CV's or Shocks. It has bilsteins.

Went for a little test drive, and yes, i think there may be some knocking from the bilsteins, but that's not it.

The knocking/grinding noise is quite weird, and audible. I only properly heard it when going quick through some left hand corners, And when going into reverse. You come to a stop, stick it in reverse, then when you go back, all you can hear is a clunkinockigigrgdg. I'm suspecting it's an inner front CV maybe?

Anyway i can test to see if it is a CV? Any ideas on what else it may be? I was going to have a look today, but couldn't find my axle stands, so flagged that for today.

find a big patch of slushy gravel, do some donuts for a few minutes, then go "nope don't know what it is-sorry"

I agree +1

[Jaxter]

No gravel was used in determining it was the drive shaft center donut that had worn and come away...

[Shale]

That explains it

Yaaaaaay replacing driveshaft time. Do not want. Glad don't has up here! ;D

[Munkvy]

Sounds like a wheel bearing to me.

Just the donut, the drive shaft is fine thank Christ...

[Shale]

Getting to it is going to be fun though.

Pity you're not up here. We have driveshafts in presumably good working order, donuts and all, coming out our ears.

Yea, funny you say that. I visited one of the wreckers here in Qt and they have absolutely nothing from a B4. But he's waiting for someone to write theirs off in the area, he said while looking at mine....

[Shale]

Nothin' down there...maaaan there is a GTB in at Pick-a-part at the moment! Pity freight is a killer because the parts are worth nothing.

And LOL here's hoping yours doesn't end up at the wrecker ><;; Dargh.

If there's a possibility of non-killer freight, there's umpteen gazillion options up here in AKL and all of us would be more than happy to make it happen, as Reubs will tell ya

[ReubenH]

Yeah, just waiting on a quote for the driveshaft doughnut thingiemabob from gerald...

I also need to locate my axle stands. I swear i brought them down, they are only vital to do any proper work on me car.... But i can't find em for the life of me. But want to take a look under the car myself and confirm if it is the doughnut, or something else. or multiple things.

Also, DAMN you and your GTB at pick-a-part.

[zarnah]

Ring roscos in ashburton if you get stuck for parts, they are the biggest subaru wrecker in nz, have everything, and they freight for very reasonable prices

Checked with your folks if they're still up north? They could make for some hilarious aircraft baggage

Its called a hanger bearing, just get someone to replace it

Thank you We're already onto it

Are they both correct - hanger bearing/donut???

[EJ20T]

if u talk to someone in the trade call it a hanger bearing, then you wont get any funny looks

[Jaxter]

It was someone in the trade that called it a donut - but he is from the UK perhaps that's why

[ReubenH]

Hangar bearing seems correct. This is from gerald

 

We sell them as a complete shaft, so from that I am guessing that they (hangers) are a major [to replace]. I have searched but can't find any information on swapping them, the only place I haven 't checked are my service manuals because they

are still in storage at the old building. I'll let you know if I do find something(because it WILL bother me). I have sold prop shafts in the past because the hanger rubber sags but that's about it.

[EJ20T]

the hanger bearing is replaceable, i cant remember if the subaru ones have a UJ after the hanger or a CV style joint, the UJ style one i would not advise a first timer or at homer to do

[Jaxter]

Thx on the info quote Reubs, I'm hoping I don't have to replace the whole shaft just for the hanger...

[EJ20T]

if subaru dont sell separate just source 2nd hand complete prop shaft

[ReubenH]

The whole shaft's not a biggie, bloody walk in the park actually, i've done several... It's just the price, $170 retail at strong.

And subies have a universal joint in the shaft. Um, woops, no, the one in the middle is a CV, the UJ's are at either end of the shaft.

Now, correct me if i'm wrong, but there's only two types of shaft for subies, Manual and auto right? Or are sedan and wagon different again? I'm pretty sure i've heard it's just auto and manual that counts.

[Shale]

IIRC as long as you don't accidentally get a 6MT one you should be okay ??? Could be wrong though.

i was going to suggest that but couldn't verify it for sure, id say that all the 1st and 2nd gen ones are the same, but gen 3????
