Death wobble

[Naohiko Otsuka]

When driving my Ineos Grenadier at around 100 km/h and hitting a bump, it starts to wobble violently
so much that it feels like the wheels might come off. It’s really dangerous,
and I want to fix it. Has anyone else experienced the same issue? The car is a diesel with 41,000 km.

Do you have any modifications to the stock steering or suspension?

Check all bolts and nuts related to the front axle! The radius arms, the Panhard rod, thexsteering rod.

If one of the bolts or nuts came loose youneed to fix thar a.s.a.p

Death wobble can unfortunately become an issue with solid front axle vehicles. It’s cause is usually worn front suspension parts (or obvious loose/missing parts), and can be difficult to identify the root cause if nothing obvious is apparent. What makes it hard to diagnose is that the suspension parts wear over time, some faster than others, and many times the cause is not a single item, but multiple worn items that need to be replaced (ball joints, steering linkage, shocks).

I’ve gone down this rabbit hole on my ‘96 Cummins Ram, and end up buying all new extreme-duty aftermarket front suspension parts each time the death wobble rears its ugly head. It’s only a matter of time before I have to do it all again. I get around 60-75K miles (100-120K km) out of these parts, so I’m surprised your’s is showing at only 24K miles (41K km). Hopefully your’s is a single easily identified part.

Most importantly is to NOT ignore it. It won’t get better over time and magically go away on its own.

This is an important question. As well, you should check the tie rod and drag link as they often come from the factory completely loose.
