2008 Chrysler Grand Voyager - Lost electric after bearing fix

Maintenance/Repairs
1

I have lost all electrical power after changing a front hub bearing. Battery is new and tests out ok. Car started ok when I drove it into the garage. I had to hammer the hub a lot to get it out. Have I activated some sort of crash sensor ?

This has to be figured out the same method you’d use if all the water fixtures in your house didn’t produce any water flow when you turned them on. Start at the water meter, and trace the pipes from there until you find a point where there’s no water. In your case your shop will have to do the same, start at the battery and probe the power (+12) voltages until they reach a point where all the voltages are zero. I expect what happened, a major fuse or fusible link has been damaged.

No experience w/your vehicle. Are there any wires or connectors you have to work around replacing the hub bearing? Only thing I can think of is a wheel speed sensor. But hard to imagine even if that circuit got dead shorted it would cause all off the car’s power to go out.

I’d guess the battery is no longer connected. Look for loose cables…both Batt (red) and ground (black). Your pounding may have knocked one loose.

If connections at battery posts look good, next is a visual inspection of the ground cable from the battery negative to where it connects w/ the chassis.

Thankyou Sir!

When I get back to my workshop, I will check cables and earth.

I will also investigate impact sensors??
I found a wiring diagram showing two of them in the front bumper !

I’m just a diy’er , no experience w/your make/model/year. But it seems unlikely triggering an impact sensor would cause loss of all the car’s electric power.

Hi George
I had family in San Jose back in the 80’s. They are now in San Fan, LA and Utah.

My car is a 2008 Grand Voyager. There seems to be problems in the UK with the 2008 model. Mine is the later square shape. I have been sent a few wrong parts this year. Now I send my VIN so suppliers can send correct parts. I luckily found a Jeep Chrysler / American parts supplier just 10miles from my house last week. These guys are fantastic.

I race a 1975 MGB these days. But it has a 383 SBC motor with TH350 tranny and Ford 9" rear end. It seems simple to buy parts for the Hybrid MGB. But getting parts for a factory made Voyager in the UK can be difficult.?

I will be back in the car next Sunday to investigate the strange problem.

Perry
