Driveshaft services: custom builds, repair, balancing and conversions

Custom driveshafts

From six measurements and a yoke choice we cut DOM or aluminum tube, press and weld the yokes in a fixture, fit new u-joints, straighten to under 0.010 inch runout and balance at speed. Lifted trucks, engine and transmission swaps, street and strip cars, off-road rigs, vans and industrial drives. Every series from 1310 to 1550 and the Chrysler and GM sizes.

Repair and rebuild

Ship the shaft or bring it in. We inspect runout, phase, yoke ears and splines first, then replace what is worn and balance the result. Re-tubing in new DOM tube is the standard fix for a dented or rusted tube and keeps your original yokes. A rebuild usually leaves the same week.

High-speed balancing

A vibration that tracks road speed in every gear is usually balance, runout or a lost weight. We spin the shaft at operating speed on a two-plane balancer, correct it with welded weights and re-check. Shafts with runout are straightened first; shafts with worn joints get those replaced, because a loose joint cannot be balanced.

Shortening and lengthening

Shortening re-uses your yokes in a new or trimmed tube at the exact length you need. Lengthening is a re-tube in new DOM or aluminum. Both are done in a fixture so the shaft stays straight and in phase, then balanced. Give us the joint-center or flange-face length and we handle the yoke math.

U-joint replacement

We stock 179 universal joints across every series and press them in while you wait on most shafts. If the yoke ears are oval or peened the joint will not last; we tell you and quote a yoke. Conversion joints let a shaft mate to a yoke of a different series without changing it.

Center support bearing replacement

We identify the bearing by stub diameter and bracket pattern from over 300 in stock, press it on driving the inner race only, inspect the stub spline and the two joints next to it, and reassemble the shaft in phase. Shimming guidance for lifted trucks is included.

Flange and yoke conversions

Conversions let a driveline from one vehicle live under another. We match flange patterns by bolt circle, hole count and pilot from 243 flange yokes in stock, select conversion joints where one end must change series, and fit double cardan heads where angle is the problem.

Measuring and consultation

Use the free driveshaft designer to draw and dimension the shaft and send it to us, call the shop with your measurements, or drop the vehicle off and we measure it on the lift. We read yokes and series off photos daily and will say when a premade shaft is the cheaper answer.
