i have found a leak on a line that it is running up behind the passinger side of the motor . there are 2 lines and they are wraped in a protective sheating. they appear to run to the power stearring resavor. is this what im looking at? and whats the best way to replace them ? Or are the lines going to something different.
Metal part of hose loose in the fitting at connection to pump. Leaked all fluid out. Nut is fully tight; still loose and leaking.
Hose fitting on the bottom of the power steering pump has a small oring,where the high pressure line connects to the pump replaced oring and has not leaked since
My son and I replaced the pump and we still had a leak. Took it to the dealer, mistake, and they said it was the rack. Got it home and 2 days later had a huge puddle on the floor. Took it back and they said it was the high pressure hose.
The hi-pressure PS hose was replaced @ 87000 miles due to seepage- not really a leak. Two qts of PS fluid was added. About 600-700 highway miles later, while maneuvering into a parking area the PS completely failed. I checked fluid level-which was OK. Left it overnite and in the morn checked for leaks under the car and fluid level in the pump- all OK. Started car and drove off as tho nothing was wrong- PS was working fine and still is @ 6000 miles later. Have checked w/ 2 Buick dealers and several auto repair shops- all totally baffled. This is a real mystery.
Power steering "stopped." Leak from power steering hose. Difficult repair - several shops would not try to fix the problem.
Once more I need repair work done to my Buick Lacrosse. This is the 3rd time in a year and a half I need the Power Steering repaired. First occurrence was in February of 2015, then December of 2015, and now April of 2016. Could the Buick dealer be using inferior products, replacing with re-manufactured or reconditioned parts?
I have selected "me too" to 3 other common problems with the Lacrosse. I contacted buick for assistance on repairs and they said Garber Buick in Saginaw Michigan would only agree to $50 assistance on a $443 repair bill. How sad! But they had no problem taking bail out assistance from my tax paying money!!!!!!!!!!!!
power steering hoses leaking. Haven't had it fixed yet. Repair cost quoted by Buick around $300 dollars.
Leaked Power steering fluid, had it checked, Dealer replaced High side power steering hose cost $1600 because it involved moving the engine to get to it.
Had fluid leak took it to my mechanic said it was power steering lines then called Buick took to them and for 50 dollars replaced lines. Then just over a year later did it again but no help from Buick. Took back to my mechanic and he spliced it so far so good. Re-call not likely. no more Buick's !!!
