Trying to make hard turn either left or right mostly while parking the power steering locks or gets really tight. Put power steering fluid in. Does nothing at all. What can I do. Looking at other post...obviously nothing.

2005 Pontiac Bonneville, clunking noise in steering. Per dealer, intermediate shaft is manufacturer known problem, while under warranty shaft was lubed, then replaced, then lubed again. Problem persists and is worse in cold weather. Steering becomes less than accurate providing improper road feedback and improper response to driver input. My concern is that shaft will fail or will cause other steering failure. This has been a persistent problem since ownership taken 4 Sept 2004.

When the right front wheel passes through standing water moisture is deflected onto the serpentine belt. The serpentine belt slips causing a loss of power steering which renders the vehicle not able steer until the serpentine belt stops slipping. Multiple occurrences.

Bonneville 6-cyl

  • Automatic transmission
  • 32,000 miles
Intermediate shaft was replaced by the dealer at approximately 32000 miles and now I have the same symptoms again, clunk in the front of the vehicle when turning. There is approximately 40000 miles on the vehicle now. Unfortunately there is no warranty left so I really can't drive the car for fear of wrecking and possibly killing someone.
