I need to purchase a front left spindle, I was hoping to get a used one. But I can't find the specific part number for my short base and the L is a different part number.

4E0407254R (long base)
4E0407253R (short base)


Does anyone know if the actual spindle is interchangeable between the L and short base? I thought I read something similar about bushings with different price/ part numbers but being identical, was hoping for the same here.

Going through upper control arm seized pin hell right now.

Thanks in advanced as always

Search this forum for my experience from May of 2014. I had the same thing on the driver's side. you just remove everything and press out the bushings and press in new ones. I actually managed to hold everything myself while pressing them on my Harbor Freight 12 ton press. With a helper, it would have been easier.

I replaced the wheel bearing & stretch bolt while I was in there so I wouldn't have to later.

Ironically, the passenger side went way easier in December, 2014 (thread also posted; search for it by my user name.

Basically, I don't understand why you need a spindle unless you had a bad wheel bearing and ruined the spindle.

Knuckles are probably a bit different since the longer wheel base requires a bit different steering geometry.

Edit: No they are not different. That's just left and right knuckle.

Maybe a strut or upper control arm removal gone bad? Pinch bolt sometimes strips out.

Mister Bally

Right, my pinch bolt broke off. I removed the knuckle and both control arms as an assembly, replaced the uca bushings and replaced the assembly. That's what I am suggesting the OP do.

Mishar,

Just to make sure I understand correctly. You are saying that the knuckles <b>are</b> interchangeable?

Or are you saying the part numbers I listed are for the L and R knuckles

Here are links to Audi Parts

Short Base Knuckle

Long Base Knuckle


So the pinch bolt snapped and I can't get the middle portion out. Its very very corroded so a new spindle is the way I was planning on going. I don't have many fancy tools. Maybe I should have taken a different route when removing the arms. If you guys think I have other options please let me know

If you do not have tools to do so, I recommend taking your spindle to a machine shop. They can definitely get that pinch bold out for you likely for under $50.00 just an idea, and much easier than sourcing a new spindle.

I am saying both of those. You listed left and right knuckles and they are interchangeable SWB LWB. Check here.

You can drill out that bolt. Go with smaller drill (6mm or 1/4"), start and stay in the center of the bolt. Not easy but doable.

Mister Bally

Maybe I misunderstood you. You are trying to remove the UCA's because you need to press out the bushings. If so, Yes, You have a cheaper option as I mentioned above. Twice.

Thanks for the reply.

I guess I should have consulted the forum before I started, but I was just going to swap out the whole control arms not the bushings, since I didn't have the press to do just the bushings. So since the bolt broke off and the bolt is refusing to come out of the knuckle (haven't tried drilling it yet), I was just going to get a used knuckle since its easier to swap it out. That was my rational.

Anyways I appreciate everyone's response as always.
