Volvo 850 stw. 1996 jacking bar broke off the bottom

[Per Groth Ludvigsen]

Hi,

Have to admit that I was very surprised today when I found out that one side
of
jack bar had loosened from the bottom leaving 2 holes in the bottom directly
into
the carpet.

Car is in perfect condition elsewhere - is it something that can be expected
or
should I claim to Volvo? I used the standard jack supplied with the car.

Best regards
Per
