Product Description

Removal of broken differential pinion shaft lock bolts in GM and Ford integral (WER) type rear ends can be time consuming and frustrating! Often the differential pinion shaft lock bolt is found in a broken state when servicing this type of rear end. Removal of this bolt is required to perform any type of service. From axle seals to complete overhaul this bolt must be removed. The removal of this lock bolt is essential in performing rear axle replacement, rear axle bearing replacement, rear axle seal replacement, most differential repairs, as well as all differential overhauls and rebuilding Although many believe this lock bolt is broken at the time of attempted removal, this is not the case. What causes this breakage is the back and forth rotation of the smaller spider gears, which causes a back and forth motion of the pinion shaft. This in turn flexes or, in effect, bends this lock bolt back and forth causing it to fatigue and break. When found in a broken state much damage and expense is incurred in the removal process. Current removal procedures include the use of hammer and punches along with torches and impact chisels (not to mention the swearing and throwing of tools!) The price of these methods range from the cost of a pinion shaft to the expense of an entire carrier plus the labor. This kit provides drill bit, drill guides, and extractors so the lock bolt may be removed in a five minute extraction procedure! The instructions are easy to follow and very thorough. All components come in a re-sealable tube for safe and convenient storage.

This kit works perfectly on Ford and GM axles. It saves you a lot of frustration and problems. This set is rather large for Dana 35 axles and similar.

I used this product on the rear differential of a 1990 Ford F150 4x4.

I'll admit - I thought for sure I was wasting my money when I bought this. But since this product is cheaper than every other part you'd have to break to get the pin out anyway, I figured it was worth a shot.

It arrived promptly, and with instructions included. The included drill bit guide bolt threads right into the hole where the broken bolt head was, and the drill bit is thin enough and just flexible enough to allow drilling in such a tight space with a standard sized household electric drill. I followed the instructions, removing the bit periodically as stated to allow cuttings to be removed from the hole. I then used the included tapered-square extractor to bite into the broken piece of the pin that I drilled into, and to my surprise it actually caught it and I was able to thread it out.

This brilliant product saved me a tremendous amount of time, money, and headaches. I went from skeptic to fan of this product in the time it took to drill a 1/4" hole. I highly recommend you try this product before attempting to cut, grind, or smash your way to freeing the broken bolt!
