    A serious Warning Check your A arms

    I wanted to bring this to the attention of all Viper owners.

    I see many Vipers where owners talk about ceramic coating, cleaning products and paintwork but how many of you regularly clean and pay attention to the underside of your cars?

    The pics below are a clear warning to all of you. This particular car was immaculate on top and a clean engine bay, the car had been garaged for over 5 years before it was recently put back on the road.

    The new owner took the car out for a couple of drives and the 3rd drive could have cost him his life!

    Both front suspension Lower A arms collapsed due to fracture cracks where the bushings pass through while out for a drive, the Koni shock absorber snapped and the front of the car smashed into the ground. I'm not going to name names but I am posting this as a safety warning to you all. The driver hit the brakes on the car while driving at about 30mph when the front collapsed. It could have been a hell of a lot worse!

    Wow, good warning.

    Just happened to a buddy of mine in his 2600rwhp Corvette. A arm snapped and sent him for a heck of a ride into the median.

    There have been at most ten of these wishbone failures that I recall hearing about over the years. Interestingly, I think 3 or 4 of them have been in Europe. It appears that the light galvanizing on the outer bushing sleeve wore through and started oxidation/electrolysis in the wishbone bushing bore.

    The upper pivot bar and shock eye bushings have some noteworthy oxidation evident on them as well.

    Hi Dean, I can tell you I have indeed seen this now on 3 Vipers in Europe, you can see that the corrosion on some of those parts has been there for some time. This car was one of the better Vipers in the UK but many owners here do not have ramps as I'm sure a lot of American owners don't have either. The damage done to the car is more than just replacing the A arms!

    Check your cars. Better to be safe than sorry.

    Most of us have floor jacks and creepers at a minimum. That and good, strong lighting are all you need to perform a reasonable inspection of these areas on your own. Some of us are a bit more OCD...

    Thats corrosion. Pure and simple. The aluminum looks less than optimal and the bushing is a dead ringer clue. Rust, by volume, makes 12x what uncorroded steel does. When that bushing corrodes it starts to exert outward pressure on the surrounding structure i.e. the a-arm. I live in a relatively dry, and certainly hot climate. My arms look factory new. But if you live coastal, wet, drive on salted roads and so on, then beware. There are certainly steps you can take to prevent that. Besides Zaino'ing the hood.

    Yep, that's the point Dave, many owners don't clean up the underside of the car so are unaware of pending issues!

    I had the upper A-arm mount that is welded to the frame fracture while driving. I actually heard it snap. Luckily not further damage was done and it was a fairly easy fix.

    For the strut shaft to break,(looks like half was cracked like it was rusty) and the multiple failure, are you sure that car never was wrecked, no hit a curb at some point that "a all it needed was a alignment"? Most were known to break on the ball joint end. the crack in the control arm was likley there by the green coloring in the crack.

    No Ryan, this car has never been wrecked (until now). The car does have a Big Brake kit fitted and 19" wheels, weather that caused added stress to the suspension parts (who knows)? but corrosion is the issue here. Time to swap out to energy suspension Polly bushes and ditch the old metal bushes.

    Put my car on the QuickJack yesterday for the routine inspection. All 8 control arms are looking good... will definitively check them on a regular basis now....
