Nothing changes nothing lost , no money spent? Then start throwing around parts money, wheel bearings, ball joints, etc. my 2 centavos.

I have this shaky feeling since i bought the car.
It was fitted with 41/2" Steel Wheels with gigantic 165 winter-Tires, now 51/2 wheels with 185 summer-tires : no change (IMG:http://www.914world.com/bbs2/html/emoticons/huh.gif)

totaly shot boge shocks allaround, now new koni: no change (IMG:http://www.914world.com/bbs2/html/emoticons/dry.gif)

rusted through hell hole and rocker, now complete solid tub: no change (IMG:http://www.914world.com/bbs2/html/emoticons/unsure.gif)

old standard tie rods, now new turbo-tie rods: no change (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif)

different toe in settings tested: no change (IMG:http://www.914world.com/bbs2/html/emoticons/mad.gif)

Things to check or change:

Ball-joints
wheel bearings
A-Arm bushings

And some shaking also. This was after moving up to 205/50 tires. I finally changed out the front struts and ball joints to a 74 models. The hubcentric feature fixed the problem. Bill Kohnke

My 914 had a bitch of a "sideways" wobble after hitting a railway track at an angle...my new Koni's diddn't fit quite right in the tube or loose in its own insert, 6 and 12 oclock movement when the car was jacked and shock fully extended. Switching to Boge fixed this. in the ass end my trailing arm bushings were OK but took them apart anyways...good thing, my near pearfect car had rust on the inside shafts so deep the rubber bushing where just being squished around... (IMG:http://www.914world.com/bbs2/html/emoticons/dry.gif) These 2 things made all the differents in the car, very hard to check and find.

Yes it is a 1970 car.

I am looking for a 5 lug conversion. Only missing parts are new break calipers.

Don´t know if try first with new ball joints or buy new 911 calipers and 2 more fuchs and do the five lug now (IMG:http://www.914world.com/bbs2/html/emoticons/idea.gif)

ball joints are cheaper.

BTW Thanks for all the good advices. I love the Club!

Unregistered	My '70 had the exact symptom yours has, and just like everyone here has mentioned, the ball joint was loose in the strut. New later style struts using the wedge pin solved the problem. But I wanted to mention a couple things that I've read here that I disagree with. First, I cant believe the problem is in the tub. After the work you did restoring it, you probably the most solid tub on the planet. Second, people have suggested tightening the wheel bearings as a means of removing play. I think that is dangerous. Front bearings are tightened to 1 ft-lb (please do the N-m conversion). If they are still loose then the bearings and/or spindle is worn and should be replaced. Overtightening the bearings risks disaster. Feel for a groove on the under side of the spindle. good luck

I changend the ball joints and the wheel bearings. As they looked, they were the first ones. Original mounted in Stuttgart (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif) Opening the nuts that hold the ball joints was areal disaster (IMG:http://www.914world.com/bbs2/html/emoticons/dry.gif) With the right tool an an impact wrench a 1/2 hour of work.... nothing happened.

Senior Member Group: Members Posts: 867 Joined: 30-November 03 From: Germany, Lambsheim Member No.: 1,404 Region Association: None	after a short testdrive i decided to change the wheel bearings also. Unfortunately no pics of that work. The shaky was a mix of a bunch of worn parts. Every step (Tierods, Ball joints, wheel bearings) made cured the shaky a little more. Couldn´t do extensive test driving because of snow (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif) but till now this is an complete different car now.

Where did you get the tool for removing the ball joint nut? I think this is the first time I have seen the "special" tool, other than in my Haynes manual. I remember the one Dave Hunt made up from pipe fittings.

I used an adjustable pipe wrench to remove them on my car. (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif)

i bought it from guy that is remanufacturing several parts, like tools, suspension bearings, caster shims, etc.
I bought it before i saw the idea with the pipe fittings, on the other side 20 Euro are not to much for this rare tool

Also on german ebay those tools appear from time to time.

Unfortunately in my case the tool doesn´t help anything to remove the nuts. (IMG:http://www.914world.com/bbs2/html/emoticons/mad.gif)

For torquing down the new nuts it was very helpfull.

Yes sometimes. But i have some .. lets say not so good experiences with them.
So i try to find my stuff at other dealers. There is one called "914 Ersatzteile Versand".

Only the best experiences, ultra fast shipping, good prices.
Some parts are direct from Porsche. In Mannheim, 30km away there is an porsche agency.

Ebay is also a good source for new and almost used parts. It´s in the mix.

There are some rubber pieces mounted n the struts. there was to less room for the strut to move free if i hit a little larger bump. I turned the spindels higher an made a test drive. Nearly now shaky anymore (IMG:http://www.914world.com/bbs2/html/emoticons/clap56.gif) But now the car looks like a stork (IMG:http://www.914world.com/bbs2/html/emoticons/dry.gif) Maybe the rubber things can be cut a little?
