Driver-side - 1991-1992 Isuzu Impulse FWD and Isuzu Stylus
however, inside the inner CV joint there is a tripod bearing mount. The bearings, themselves, are smaller diameter in the Elan. Also, a key difference is
the Isuzu/Storm uses a coarser splined axle. You will need to remove the tripod bearing in the original Elan CV joint and replace them with the larger bearings
of the Isuzu/Storm joint. This way you are using the finer splined tripod mount (Elan) with the larger bearings (Isuzu/Storm). This way you get to use an
Isuzu/Storm inner CV joint on an Elan. $42 for a new Isuzu (aftermarket) driveshaft verses $300 for the Lotus inner CV joint.

5. Elan M100 power steering pump is 99% identical to Isuzu Impulse or GEO Storm.
Only the high pressure line is threaded for a female fitting and not a banjo bolt (like on the Elan). This banjo bolt extension can be swapped from
old Elan pump to new Isuzu/Storm pump. Then 100% identical. |
