Subaru Repair Questions? Ask a Mechanic for Answers ASAP
Hi..there..Im Rob, A fully certified vehicle technician in the UK and will be assisting you with your question today.
How do you mean "bumpy sensation" - is it like the steering goes normal then binds then normal again as you rotate the steering in either direction?
Does this happen when sitting stationary rotating the steering or just moving?
If you feeling a rotational bumping or intermitent binding effect in the steering wheel..then by that you could well likely have worn UJ joint in the steering column..normally the easy way to test that is to get access the uj joint nearest the floor or steering rack..have the front end jacked up off the ground..and rotate the steering wheel by hand slowly whilst listening or observing the rotational movement of the uj and see if you can spot it bumping as it rotates..or check for any loose play in the joint..further investigation could be to undo the both track rod ends and the rotate the steering..and that should kind of narrow down and eliminate anything further to the steering rack or column..
If its bumping sensation on full or near full lock and felt through the floor of the car or steering..then its quite likely a Driveshaft CV joint...
