Looking to get a dog bone and possibly motor mounts, wondering if there's any recommendations where to get them and hardware without paying an arm and a leg. Was looking into febi mounts but let's hear whats good
I replaced Dogbone mount on my 2005 and was unhappy with the non OEM stiffness in cold weather. I ended up using the big end mount from an aftermarket Dogbone and the rest is my original with the original big end bushing. The original big end mount was destroyed when I tried to remove it, not unusual if it has seen lots of salt. Using a small 3/8 ratchet the bolts sheared like butter inside the mount. Galvanic corrosion between the aluminum and steel eats the steel and causes the bolts to seize inside the mount. Once the mount was off I could almost remove the rest of the bolts with my fingers.Thanks for the links and info, does anyone have the thread pitch specs on the bolts for mounts or dogbone? On BFI i found this: (doesn't include thread pitch)
N-905-970-05 10x70mm bolt (qty 1)
N-102-683-04 8x45mm bolts (qty 2)
N-102-466-10 10x30mm bolt (qty 1)
Hey_Allen are these the bushings you were talking about?

Is this a viable option or replacing the whole thing better, thoughts?
you're talking about these from idparts?M8x1.25 and m10x1.5... IDPARTS has a good alternative Dog bone and has bolts too. Use an impact to remove them if you can, the quick snap will hopefully break them loose. I used and a ratchet on my first one and snapped the first bolt. Used an impact on the next 2 and they came right out.
i do deal with cold and snow, ive read less than impressed reviews on poly bushings so ive been planning on using oem rubber ones. not sure whos idea it was to put steel and aluminum together but had my calipers strip out cause of that. but yea im thinking just getting a whole new dogbone may save a bit of frustration. thanks for the info! :thumbup:I replaced Dogbone mount on my 2005 and was unhappy with the non OEM stiffness in cold weather.

For some reason I never could figure out the new long piece of the Dogbone would not work with the OEM bushing. The engine sat in the wrong orientation and I had to reef on it to get the vertical bolt in. I had the Dogbone apart and back together in every orientation I could think of then when I went back to the original long end it went in like it was made to first time.
That said if you have cold weather to deal with I would seriously consider the OEM rubber from BFI in your existing Dogbone. Get a cheap aftermarket unit as well so you have options and parts to combine in case you shear the bolts. If the bolts shear the only thing you can do is cut it apart.
Not me.anybody opposed to the idea of just getting some US grade 8 spec bolts instead of the oem mount ones? curious if there would be a difference or reason not to
10x1.5 70mm bolt
8x1.25 45mm bolts
10x1.5 30mm bolt
Alrighty makes sense, I just struggle with paying places like ECS 70 bucks for a full bolt kit but I'll hunt them down and plan on using oe vw ones. I think Im just gonna start with replacing the dogbone and go from there.Not me.
Keep in mind that the VW bolts, if they are in fact stretch bolts, will hold better, as in won't back out as easy.
If you do use a standard SAE Grade 8, you'd use the maximum torque for those and not the odd torque sequence called for in the instructions.
To be on the safe side, most of us will recommend the stretch bolt.
Maybe one of the mechanics on here can recommend what they use.
PB Blaster is good stuff.Sweet good to know man thanks a bunch that's what I was planning on doing, spraying some PB Blaster then loosen them up
And grade 8 is not a grade for metric bolts. You would want 10.9 as turbo mentioned.Most stock VW bolts are grade 10.9
Thanks, I mistakenly referenced an SAE grade 8 bolt, which would be fine, except they don't make those!And grade 8 is not a grade for metric bolts. You would want 10.9 as turbo mentioned.
