HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

x-member bolts working loose??

Post  948inVA on Thu Dec 13, 2012 5:57 pm

Just wondering if anyone had their cross member bolts work loose due to the poly engine mounts? I just got my car back from the alignment shop, after they tried and failed again to get the car aligned properly. On the drive home I heard some clunk noises going around turns and could feel the engine shake the steering wheel going into my driveway. Well, I put it up on blocks and checked everything out... and the cross member bolts were finger tight!! WTF?! Would they have loosened those to do the alignment, or could they have worked loose over time? I'm already never taking my car back there.. they tried to tell me they couldn't get more than 2.4* caster because the header was in the way. Rolling Eyes

I don't see why they would have ever loosened the crossmember bolts. I will be checking mine. Do you get a lot of vibration from the engine?

Loosening and shifting the subframe is the only way to set cross camber on many of the Audis. But if you're running camber plates that's not necessary. I was able to put another quarter turn on my crossmember bolts after the first track day but they didn't feel loose and have stayed tight since.

Nope.

You should triple check your engine to make sure it isn't contacting the crossmember anywhere. With my stuff my oil pan was slightly contacting one of the rack and pinion mounting points. I ground it down and my vibes went down a lot.

Arthro, my engine feels pretty smooth and I don't have any noticable vibrations. I'm running stock upper strut mounts.. and there looks to be plenty of clearance between the pan and the rack mounts (I'd assume the paint would wear off if it was hitting). I'm just wondering how long they've been loose like this, because it might explain why I've had so much trouble with the steering wheel shimmy at highway speeds. Are you guys torquing them to 63 ft/lbs?

No issues with those bolts working loose, but I have had an issue with the motor mount bushings deforming and then the oil pan binding up the steering rack because it's sitting on the rack...

My motor was having vibration issues with the old motor mounts. I am pretty sure the passenger side mount is separated from the mount at this point. I obviously have to pull the motor to have it rebuilt, so I have TPC's Pan, filter relocator and the newest motor mounts. My header started hitting the frame rail out of nowhere. Cant wait to get it out and get it rebuilt.

I'm on my 3rd set of motor mounts. Eric's original set, than Eric first revised new set and now Eric's second revision motor mounts. I can tell when they've collapsed because my steering gets heavy and sticks, it won't self center. A quick peek under the car confirms it as the oil pan is sitting on the steering rack.

Eric's been great to deal with, as to be expected.

Same thing with none now that I think about it. So do we just go 100% solid? Do you think the latest will hold up?

The new bushings look a lot better. They're one piece and have a much more solid dowel pin going through them. I'm concerned that the solid motor mounts will result in a cracked upright.

I'd routinely check the uprights and mounting brackets for cracks
