[Laid Often]

Hi, I was wondering if anyone has had a similar problem as me. I recently built a 64 impala convertible. I installed 2 cce competition pupms with 8 deka batteries 1250 cca. The car is waesome but after two weeks of mild hopping max around 24 inches, and 2 days of 3 wheeling. The passenger side axle or the drive axle slid half way out of the rear end. Obviously parts need to be replaced although i have yet to inspect it. Is there any way to prevent this from happening in the future? Along with the hydro set-up i also installed a new telescopic rear driveshaft with all new yokes and a heavy duty carrier bearing, an air-ride technologies panhard bar. Reinforced the rear trailing arms and did not alter the banana bar. The rear cylanders are 14'' Any helo would be greatly appreciated. I just want to figure out if it was the rears time to go, or if the hydros caused the failure and if so how to remedy to avoid furtjer incidents. Thanks again.

tack weld the bearing retainers to the axles, or get a 9" rearend. This is common on impala's.

All the weight and reversed wires puts a lot of extra stress on the bearings. the retainers loosen up and the axle slides out. Its not just from locking the car up.

this isn't the best solution as when you tack weld, you're welding to a hardened half shaft, which will make it weak at the wel dpoint and it will break after time. I know two people this has happened too and its been pretty disasterous in both instances.

The best solution, apart from a ford 9" are race spec halfshafts and bearings which have a greater load capacity :thumbsup:

I have tack welded those and had trouble with shearing the axles in half. About 8 years ago we start drilling and tapping the retaining ring to the axle and have not had a problem since. Right now the car is doing 60"+ and hittin a hard ass three-wheel.

I have not used the drill and tap methode but I can say from experience DO NOT WELD THE AXLE. We broke no less than 4 axles on my boys 62 doing it that way. I would not mess with the stock if you plan on keeping the car, just go get a 9" with big axles. There has been a recent post about Toyota truck rear ends also you should check out.

At least it was understandable.
