Automatic Transmission
EVERY TIME WHEN I STOP THE TRUCK OR I DRIVE AWAY FROM A TRAFIC LIGHT OR SO AFTER A STOP, IT GIVES A HARD HIT TO THE TRUCK.
A FORD DEALER TOLD ME, THAT THIS PROBLEM IS KNOWN, IT WOULD COMES FROM THE REAR AXLE, CAUSE THE SHOCKS WERE TO SMOOTH AND THE REAR AXLE MESHING WOULD BE TO HUGE.
IS THAT TRUE? AND KNOW, I HAVE THIS HARD HITS ALSO BY DRIVING AT THE HIGHWAY WITH ABOUT 65 MLS, UPHILL.
WHO CAN HELP?
I may be able to help you here. I bought a 2002 Ranger Edge with 27,000 miles on it and it had the same symptoms as you describe. A thumping/bumping when I applied throttle from a stop.
I did a search and found that we are not alone. It seems that the slip yoke on the driveshft (made by Spicer) has a lubrication problem. I don't know if they should've put more grease or used a different kind, but it seems like a fairly common problem. I checked with my Ford dealer and they said it was NOT covered under the warranty. My impression was the fellow I talked to didnt know what I was refering to so he responded with what came natural..."Thats not covered"
.The good news is the fix is fairly easy if you do any work on autos. Remove the drive shaft...lube the slip yoke...and reinstall it. OK...so there are a few steps to follow so that one doesn't create more problems. You have to mark the alignment of the front shaft with the rear so it is exactly the same as it was before you started. I did a search in the Ranger forum or the interent and found detailed instructions. The only tools I used ; 12pt/12mm socket, a 16 penny nail to open the metal clamp, 12pt/12mm box end wrench, ratchet or breaker bar. The nail may not be recommended...it was all I had at the time and it opened the crimped clamp real well =).
I did a search in the Ragner forum, keyword-"drive shaft" and found the following thread. Great discussion about the subject. "Will that common driveshaft problem destroy anything?"
I will post any further information I may come across.
Good luck!
