Need to replace a pin/ bush ?how difficult is this.?

i have a laguna and i have a pin/bush that needs replaced on the nearside anti roll bar .i was just wondering if this is a difficult job and how long a job do i expect it to be|||If its the anti-roll bar link you are meaning?This is usually broken by corrosion.You may need to hacksaw off the old one?Fitting a new one isn't too difficult,but you need to compress the bushes with a lever on the top of the pin to get the nut back on.Hope this helps
