I replaced my front struts on my 03 NBC. I tried a spring compressor to collapse the right strut enough to remove it but I could not get that to work so I lowered my subframe just enough to get the right side strut in and out, as some folk have suggested. That worked very well.

I know that VW states that these subframe bolts should be replaced if loosened, but some of you have stated that you have re-torqued the old bolts without incident. Since I am not going to have time for a few weeks to drive 50 miles to our nearest VW dealership, I need to torque these old bolts for now.

Per my Bentley Manual, new bolts are supposed to be torqued to 74 ft lbs and then wrenched another 90 degrees.

How much torque should be put on these old bolts that I am re-using? I have torqued them to about 80 ftlbs but was afraid to guess how much more to put to it for fear of breaking a bolt.

Thanks for your help!

ZERO tourque on the old bolts!!!!!
These are one time use bolts similar to the motor mount bolts and should NOT be reused.
Yeah, some folks will tell ya it's OK, or they have done it themselves but I would strongly recommend you replace them with new bolts ASAP.
All it takes is that one pothole or speed bump or dip in the road to cause those old bolts to give. Re-tourquing stretch bolts will give you a false read on the tourque wrench because they have already been tourqed once to their limit and doing it again stresses the bolt and threads beyond that limit.
So, roll your own on whether to replace or not but if it was me I'd never do it.
I'm just sayin....:)

I certainly prefer to replace the bolts....

Would ANYONE by chance have a means to look up the part numbers for the two large bolts that attach the subframe to the body?? Maybe I can find an online store to order them from. Anyone know an internet parts store that would stock these bolts? I called my VW dealership and I had a difficult time making them understand which bolts that I needed. My VW dealership is 50 miles from my home and 75 miles from my work place.

I guess that I also need to replace the lower bolts that attach the shocks and struts also...the shocks and struts came with new bolts/nuts for the top but not the lower ones.

Thanks for your help!

I found the bolts and the part number. ESC Tuning seems to carry them. The subframe to body bolts are N90752802 and run about $15 each.

ESC also carries the shock and strut lower bolts and nuts in a kit. The shocks and struts that I purchased came with new upper mounting bolts but not the lower bolts and nuts that should also be replaced per VW.

So as not to confuse, all of these bolts are to replace the bolts that secure the front subframe to the body. There are two bolts that I loosened on the passenger side to cause the control arm to lower in order to get the old strut out and the new one installed. (Frankly, since the spring compressor method did not work for me and after the cost of these bolts and the tools I had to purchase to change out the front struts I wish I had just taken it to the shop...at least I know everything is torqued correctly)

I found the bolts and the part numbers. ESC Tuning and Idparts (who cater mostly to TDI owners) carries them.

The subframe to body rear bolts are N90752802 and run about $15. (VW sold me two of these and told me that they were for both the front and rear bolt up of the front subframe. After removing my bolts I saw that they were wrong...My VW dealership parts counter do not have a clue...maybe yours is better...what they sold me was the rear bolt for both sides of the car)

idparts.com carries these:
http://www.idparts.com/catalog/advanced_search_result.php?keywords=n90752802&x=4&y=4

ECS also carries these: http://www.ecstuning.com/Search/N90752802/ES257096/

The FRONT subframe to body bolts part number seems to be N90734902 and run about $8. I have not received and installed this bolt yet, but the photo looks correct. I purchased this bolt from idparts.com:
http://www.idparts.com/catalog/product_info.php?products_id=1833

ECS also has them: http://www.ecstuning.com/Search/N90734902/ES6949/

The bolts and nuts that are supposed to be replaced on the front struts and rear shocks (struts and shocks came with new upper nuts and the rear shock mount came with new bolts, but none of the lower hardware was included) are as follows (I installed them today and they fit):

Bolt for lower rear shock: N90517304
Nut for lower rear shock: N10286102
Bolt for lower front strut: N10207803
Nut for lower front strut: N101064

Idparts.com sells the rear bolt/nut as a set:
http://www.idparts.com/catalog/product_info.php?products_id=909

ECS sells the front bolt/nut as a set: Their stock #5847
http://www.ecstuning.com/Search/N10207803/ES5847/
ECS also sells the rear bolts and nuts.

If these part numbers have already been listed on the forum I did not find them. Anyone who choses to replace the passenger side strut via the subframe lowering method will need these.
