Audi UR Quattro Rally Build

8 minute(s) of a 357 minute read

Scattered progress since our last update but progress non-the-less.

We started to attack the drive shaft last week. The CV joints seem a bit stiff so we are going to clean them out and see if we can save them. If not we think we can replace them. The universal joint in the center seems fine but we might have to destroy it removing the center support bearing which is also fine but whose rubber bushing is decidedly squishy.







We also started refurbishing the fuel tanks. Initial inspection revealed only surface rust so we cleaned it out with some dish washer detergent.







We had a visit from the guys who run DIYAUTO.com https://www.diyauto.com/ last week, Nick and Steve Balistreri. DIYAUTO.com’s goal is to collate all the cool information in the various forum build threads on the web so the information is easy to search and the knowledge is not lost to us auto enthusiasts. We are proud they have both our quattro builds and our 911 build on their site.





We continued to dismantle parts that are being sent out for refinishing. This week it was the turn of the suspension components. These did not want to come apart and the students learnt a great deal about persistence and the use of heat wrenches.






We’re not even sure we can get replacement ball joints and bushings for this stuff and may have to fabricate our own.



We optimistically mocked up the rear calipers again to see if we can make them work. Both the handbrake cable and the brake fluid line want to go through the rear axles but as we intend using a hydraulic handbrake we wanted to see if we could make a banjo fitting attach. Think not:





Next update we hope to share some news about the shell. Stay tuned.

Been working on a few things but nothing too exciting. we finally found some proper UR quattro rear brake calipers

You can see how the handbrake cable and brake line come in from the back instead of the side therefor avoiding the axle.

Amanda made some more incremental progress on the model. She says she's going to paint the stripes next.

Then we started on resealing the rear differential.

No wear groove on the input flange

Rear diff is back together with new seals. Now we need to decide what color to paint it.

Amanda has started painting stripes on the model.

We borrowed an OE refinished rear caliper and decided this is the way to go with ours.

In anticipation of panels showing up Thompson Racing Fabrication took the car out of storage and delivered it to Cherry Classic Cars. We must admit it's nice to get re-acquainted.

Now we just need our wide body kit.

Panels did indeed show up from Europe from Cool Wheels in Latvia. Cherry Classic Cars wasted no time in offering them up to the body. As expected with composite reproduction panels it's going to take quite a bit if fettling to get a good fit.

They also set about fixing the rust on the shell and other minor repairs.

Before applying primer.

The shell is still at the body shop: Cherry Classic Cars in Michigan but we recently went to visit it and to make some decisions about how to put it together.

We also found a kevlar composite trunk lid in Canada

and received some vintage gauges and switches from another quattro aficionado.

More wide body progress on the rally build. Front and rear fenders are being wrestled into place by the guys at Cherry Classic Cars:

Starting to look like a car again.
