Got the axle out after removing the shock bolt and pulling the wheel hub sideways. Still need to remove the coffin arm and the e-brake cable. On first try the cable doesn't want to fit through the wheel hub (I do have the pieces off the end and there is just very end left (an eye) but it doesn't seem to fit through the hole. More research tomorrow.

I got my son to crank on it and remove those bolts, way more than 60 ft. lbs. he estimates. I got the axle loose at the wheel hub using my air hammer but can't seem to find the space for the axle to back outof the wheel hub. I jacked up the wheel hub a bit but it doesn't seem to give me much more room. Is there a trick? Or do I need to remove more parts. I wanted to remove the axle so I could get better access to the nut on the coffin arm, but the socket hits the CV boot. I can get a wrench on it but it only moves .1mm before I hit the other arm. I'll take another look later this evening when things cool down.

Thanks, JFP. I'll give it another go in the morning. Not sure if that axle has ever been off the car or not, maybe over-tightened or I'm just getting weak.

I am experiencing some strange tire noise and tire wear at my right rear wheel. The right rear tire has lost half its tread compared to the left rear and is making some noise (sounds like a small motorcycle behind me). With 152K miles I decided to replace all rear suspension components. I wanted to remove the wheel hub and take it to a shop for a diagnosis on the wheel bearing. Bentley says I have to remove the bolts holding the CV axle at the transmission, so far they won't budge. I don't recall removing those when rebuilding the front suspension. If I disconnect all components from the wheel hub and leave the CV axle connected at the transmission am I asking for trouble? Any help is much appreciated! Thanks in advance, Jerry

I decided to order all the coolant hoses for my 99 C4 (got them from Pelican) as they are now getting pretty old. I stopped in at my independent shop yesterday and was told that they have done this once for another client and the labor (inclusive of a water pump R&R) was 22 hours. Anyone out there know if this is reasonable? There are a lot of hoses (and coolant vent tubes) but I'm thinking of breaking this up into smaller jobs over time if its going to cost $2K in labor to replace the coolant hoses. Any info is much appreciated, Jerry

I have a 1999 Carrera 4 and need to replace my rear tires. I'm currently running Continental Contisport Contact 2's, 225-40-18 in front and 285-30-18 in the rear. Since my front tires are at about 50% and the Contisport Contact 2's are discontinued the Tire Rack recommended the Extreme Contact DW tire. The 285-30-18 tire has been on back order for several months now but the 285-35-18 is available. Is this a good choice for me or should I wait longer? I am at the wear bars on the insides of my rear tires and fear that I'm going to get into trouble on a wet day. Thanks for your time, Jerry

interior color code
Jerry996 replied to bigpeps52's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)
I have the same exterior/interior codes on my 99 C4 and initially thought BB was graphite grey but it is space grey. -
I thought that I'd end this thread with the answer to what finally solved my problems. Perhaps this will help people with similar issues. The electronics in the Throttle Body turned out to be the culprit. I had changed out the MAF with no change and the dealer remapped the ECU with no change. The throttle body was cleaned thoroughly and that also rendered no change. I took it in to my independent who drove it from cold one morning and he noticed a lot of noise (loud clicking sounds) coming from the throttle body. The codes retrieved at that time were P0102, P1503 and P1506. P1503 and P1506 were not present when this issue began. I ordered a new throttle body upon the recommendation of my independent, it took about 15 minutes to install and voila. No more surging, no hesitating, no ABS/PSM lights etc. Throttle response also seems much smoother now. Hope this helps someone and thanks for all the input. Jerry

According to Sunset Porsche the throttle jacking unit is part of the throttle body electronics. According to them it is only available with the throttle body, not on its own. A fairly reasonable price was quoted for the throttle body, around $220.

Throttle Body 1999 C-4
Jerry996 replied to Jerry996's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)
Yes, it is a Carrera 4, so Motronic 7.2, I'm sorry if I wasn't clear enough. I swapped out the throttle body this afternoon, it took about 15 minutes and is a very straight forward swap. The gasket is also very simple to swap out. I drove the car this afternoon, it had been parked for four days and no surging or hesitation at all (first time in ages without cold start issues.) I will drive it in the AM when it will be around 45 degrees and see how it behaves but I believe the electronics (throttle jacking unit) incorporated in the throttle body was the culprit. The throttle body was actually reasonable for a porsche part, around $220. If I still have issues in the AM then I'll report back, if not, problem solved! Thanks for the input. Jerry -
Throttle Body 1999 C-4
Jerry996 posted a topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)
I'm changing out the throttle body on my 1999 C-4 with e-gas next week and was wondering what to expect. I looked in the DIY forum and here but did not see a posting that describes it. Can I re-use the bolts? Does the ECU (DME) need to re-learn the new throttle body? Any special tools needed? I'm changing it out because its making lots of funny noises and does not behave well when cold (surging hesitating) codes are P0102, P1503 and P1506, once it warms up all is fine. Already replaced MAF with no change. Any information is much appreciated. Thanks, Jerry -
I need to order this part and neither Sunset nor Pelican knows what it is. I have a 1999 Carrera 4 with E-gas, part number or any information would be much appreciated. Thanks for helping a newbie, Jerry.

When you say "throttle jacking unit" does that mean throttle position switch (996-606-116-00-M14) or something else? I can't seem to find a part named throttle jacking unit.
-
Well I didn't know that the "throttle jacking unit" attached to the unit. thought maybe it came with the throttle body if replaced as a whole. Which is why I posted the question. All the mechanic told me was that the throttle body was extremely noisy and possibly needed to be replaced. Could the noise be from the jacking unit? Could both need replacing? Is the jacking unit serviceable? If you can send me a part number then I'll order the jacking unit and see if that does it? Thanks, Jerry
