After Wilson fired over the top, United went in front courtesy of a superb team goal with Daehli picking out the overlapping Louis Rowley and his deep cross was rammed home on the volley by the energetic Weir. In the closing stages, Bolton hit back when Clough executed a perfect free-kick past Sutherland's despairing dive to level matters.
However, there was still time for more drama as Paul McGuinness' side showed the character that United are famed for. Barmby juggled a Donald Love cross before helping the ball on to Wilson, who kept his composure to drill in his 13th goal of the season.
United: Sutherland; Love, Ioannou, Grimshaw, Rowley; Weir, Rudge, Pearson, Daehli; Barmby, Wilson. Subs not used: Byrne, O'Hara, Rothwell, Gorre, Evans.
