there are two tid-bits to pay attention to from what I've learned here....the first is that the recall procedure involved both welding and riveting. If you see nothing but welding, it was done wrong. The second is that if the reinforcements in the front are installed upside down, one of them effectively prevents the oil filter from being removed (I think it was the oil-filter anyway, but if I'm wrong, it's some "interval-replacement" component).
Here's a long, but worthwhile read on the whole subject that I found when I was researching this. Good for any Viper owner to know.....
In May of 2002, Henry Cone (renowned Viper racer, Regional officer, and ENGINEER) posted:
"Guys, I'll try to shed more light on this recall. I now have a copy of 998 and have reviewed it in detail. There are several suggestions that I can offer from this.
1. Don't panic!! And don't get in too big a hurry to get this done - be sure that you have inspected your car so that you know what you are getting in to.
2. Recall 998 is for all 96 to 99 cars up to a build date of March 1, 1999 - these cars require inspection of both the steering rack mount welds as well as the left side differential mounts. Recall 999 covers 1999 and 2000 cars and only requires inspection of ths steering rack mount - there was apparently a running change to the rear frame differential mounts.
3. THIS IS IMPORTANT - Most cars (I would guess 98+ %) will not have any cracks and will require only the addition of the steering rack mount reinforcement pieces (both 998 and 999) and the differential mount reinforcement pieces (recall 998 only). Cars most likely to have cracks are ones run at the track on Hoosiers or slicks, dragged with slicks or other high traction drag tires. or that have been damaged in an accident. We have numerous Viper Days events on both of our cars with me in the gravel traps on several occasions and Janni having hit a wall hard enough to break the steering rack assembly but neither of our cars show any cracks. How do I know?? We inspect them after each and every track event.
4. For the front (recalls 998 and 999), if inspection does not reveal any cracks then all that is required is the additional of several frame reinforcement pieces. One of them does require welding and there are very specific instructions in the recall as to how this is to be done. The other 2 pieces involve grinding off some existing gussets and replacing them with larger ones that are riveted in place with numerous structural steel rivets. Except for the welding this reinforcement is relatively straight forward as it does not require any dissasembly, etc. NO ALIGNMENT WORK IS REQUIRED UNLESS CRACKS ARE FOUND!! So the only difficultly is applying the recalls to most cars is the welding.
5. For the rear (recall 998 only) the directions require that the differential be removed to do the inspection. If no weld cracks are found several frame reinforcements are added . The one on the right side is relatively straight forward. The one on the left side is more complicated but neither requires welding. Both of these reinforcements are riveted in place with numerous structural steel rivets. AGAIN NO ALIGNMENT WORK IS REQUIRED UNLESS CRACKS ARE FOUND!!!
6. The labor time shown for the front is 2.6 hours to inspect the steering rack mount and add the reinforcements if no weld cracks are found. This seems very reasonable.
7. The labor time shown for the rear is 2.7 hours to remove the differential, inspect the mounts for cracks, install the reimforcement pieces, and reinstall the differential if no weld cracks are found. This seems to be pushing it a bit but is not too far off - the actual time may vary depending upon the exhaust system on the car as this will have to be partially removed to remove the differential.
8. THE ABOVE SHOULD BE ALL THAT IS REQUIRED FOR THE VAST MAJORITY OF CARS!!! My suggestion is to inspect your car for weld cracks yourself and / or make sure that they are absolutely present before authorizing anything other than adding the reinforcements. DON"T ASSUME THAT YOU HAVE CRACKS AND WANT THE MORE DRASTIC REPAIRS MADE!!! The reason that I say this is that if cracks are present the recall repair procedure is involved enough that it will require a very good and careful tech to get you car back to being right. And complete alignments will required for each end of the car that requires the full recall repair procedure. My fear is that an incorrectly done full recall could leave a car worse off than before the work was done!!!
9. If steering rack mount cracks are found in the front, the repair procedure requires the complete replacement of the steering rack mount with a new one. This is very involved and getting the new one welded in place in exactly the right position is going to be difficult and tedious. After a new rack mount is installed the reinforcements are added. Then several hours of front end alignment work are required. 2.0 hours of labor is allowed for changing the mount with some portion of 3.4 hours af total alignment time allowed used for the front end alignment. My view is that you don't want to have to have this done unless it is absolutely necessary.
10. If differential mount cracks are found at the rear things get really involved. Because of the welding required it is necesary to removed the fuel tank from the car. Several reinforcement pieces are welded in place to reinforce the rear frame about the differential. The welding required is involved and extencive. The total time for the rear differential mount repair (including removing the fuel tank) ranges from between 6.5 and 7.6 hours depending upon the car (coupe or roadster) and how bad the cracking is. Again some portion of 3.4 hours of alignment is also required to get the rear suspension aligned correctly. Again my view is that you don't want to have this done unless it is absolutely necessary.
