To study effects of configuration mixing on the forward angle $J$ dependence in $l=3\mathrm{}$ stripping and pickup reactions, angular distributions for the ($d,p$) reaction on ${}_{}{}^{48}{}_{}{}^{}\mathrm{Ti}$, ${}_{}{}^{50}{}_{}{}^{}\mathrm{Cr}$, ${}_{}{}^{54}{}_{}{}^{}\mathrm{Fe}$, and ${}_{}{}^{58}{}_{}{}^{}\mathrm{Ni}$ have been measured for those final states which contain most of the $f_{\frac{7}{2}}$ or $f_{\frac{5}{2}}$ single-particle strength. At an incident energy of 19 MeV, these ($d,p$) reactions (with an average $Q$ value of 6 MeV) correspond to the inverse ($p,d$) reaction measured at an incident energy of 25 MeV. The present data therefore can be directly compared with the ${}_{}{}^{56}{}_{}{}^{}\mathrm{Fe}$ and ${}_{}{}^{58}{}_{}{}^{}\mathrm{Ni}\mathrm{}(p,d)\mathrm{}$ data of Glashausser and Rickey. Significantly less $J$ dependence is found for transitions to final states for which configuration mixing effects are unimportant. This observation thus strongly supports the explantion of the forward angle $J$ dependence in terms of configuration mixing.
