2012 TC shake/shudder on light acceleation

Recommended Posts

Get a shake/shudder thru steering wheel and floorplan while under light acceleratin at 50 - 55 mph. Let up on gas, shake stops. Any ideas or similar experience/resolution? Dealer replaced coil and spark plug but still occurs. Thinking may be a cv joint or bearing issue.

I have same issue w/ 2010 XLT wagon w/ 79k miles. First noticed the issue during a short freeway jaunt during frigid winter weather. At first I thought it was rough road. It quickly worsened & became very noticeable in steering wheel, accelerator pedal, seat & floor - a rotating roughness/vibration as though bearing related. Then, pronounced steering wheel wobble developed...luckily I was near an offramp to get back on suburban surface streets. This all unfolded suddenly w/in about 5-10 miles at about 65 mph. This is an extra vehicle, and I didn't wish to incur a big repair bill at the time so I resorted to only using it on surface streets w/in the city where I live. At speeds around 30 mph in stop/go driving there is no issue.

The UK Transit User Forum has some posts that reference a number of related issues traced to CV joints, driveshafts, half shaft bearings, etc. However, it's a little tough to sort out which of these might apply to a model year 2010-on TC sold by US dealers, as the Transit has been around for a number of earlier generations overseas before it was imported for sale in the US.

The TC is still uncommon enough in the US that I don't have confidence a domestic independant repair shop will be able to diagnose this accurately. So, I finally took it to a respected import repair specialist during warmer months; they freeway drove it to further to a nearby suburb, but could not detect any issue. Now I feel at the mercy of the dealer (with access to TSBs, etc) to diagnose this correctly, but I'm still leary that a service writer on commission will replace both half shafts/front struts/wheel bearings, the steering rack, and any other related steering components and say "Now it's fixed". Sure! If a guy experiments with replacing enough spendy components by trial & error at someone else's expense, he'll eventually solve the problem! So, I'd sure like a better idea about what this issue is before I take it to a dealer.

I had an intermittent wobble. Best felt at moderate speeds with a little load on the steering wheel, like a very slight turn or an offramp at slow speed. Today swapped to winter tires and the wobble is gone.

Looks like both front tires had some damage which was not visible and not apparent when the damage side of the tires were off sync but exposed when the damaged parts lined up and multiplied their effect.
