Hi Everyone,

I am getting ready to change motor mounts in my 05 Passat TDI and was wondering if anyone could provide dimensions (preferably metric) of the subframe alignment bolts (VW tool 3393). I have the tools and material to make them myself.

Thanks in advance for the info!
Cheers,
-Tom

I can't find my micrometer but you can use a socket if it's the right size. The tools are a perfect fit for the holes and have a little lip at the top so that they don't fall through. I can rent them upon request if you feel like using them.

If it's that much of a perfect you're talking hundreds of an inch, right? You'd have to have the perfect socket!

Thanks for the suggestion and the offer. I'll contact you about the rental if I can't source anything locally.
Take care,

Sub-frame alignment issue

Hi Everyone,

I don't know the tool diameter, but I did measure the hole diameters of the top and bottom parts the tool would go into.
0.777"-0.780", don't have a metric caliper but conversion is simple enough.
The reason I revived this thread is that I will be changing the motor mounts in the future and the drivers side set of 3 holes this tool goes into do not seem to be aligned very well currently. I dropped a couple of long sockets that were smaller than the above dimension and they would not fall thru due to a misalignment. The 3 holes were not concentric.
So my question is; after replacing the mounts and aligning both sets of 3 holes, will this realignment result in negative results overall?:ugh

If your tire alignment is OK now, you might. I don't know why they aren't aligned now, with all 3 aligned perfectly, the tool slides in and out smoothly. Since the suspension is bolted to the subframe, if it's off the tires can be crabbing.

The tires have not experienced unusual wear over the last 94k miles, so it looks like a possible wheel alignment in addition to motor mounts.
Thanks for the reply.
