U joint replacement
The front u joint in my 85 GSL-SE is worn out. My mechanic tells me that it cannot be replaced because it's held in by "punches" in the housing, and there's no groove in the housing for a clip spring to hold a replacement u joint. He says I need to buy a new driveshaft.
Does anyone have a solution to replacing the front u joint, or does anyone know where I can buy a new driveshaft or have a u joint replaced in my old one? Thanks, John |
Yeah they're not replaceable. Not sure about NC but in Los Angeles, there are several driveshaft shops that cut and weld new yokes and install replaceable u-joints on a stock driveshaft. Minor problem is that the new u-joint is larger than factory so the heatshield needs to come off for clearance

Thanks. I'll look for a driveshaft shop around here.

The 83-85 u-joints can be made to be serviceable on the stacked u-joints. I just had it done on my 1985 GSL. Code me $100 but I'm sure it can be done cheaper. Here's a pic. I went ahead and powder coated mine. This is what I used. The drive-shaft shop had them in-stock.
u-joint part number 430-10A IIRC Staked-In U-Joints http://i1133.photobucket.com/albums/...ps92876533.jpg |
Thanks man! I've located a shop locally that carries the Rockford u-joints

Mazdatrix stocks an aftermarket driveshaft for about $300. They incorporate traditional replaceable u-joints so you can rebuild them if you ever wear them out.

I had my driveshaft rebuilt awhile back.
GSLSE here. Most driveshaft shops can hook you up. My U-joints were replaced a little while back when I couldn`t find a used Rx7 driveshaft. I think they used a Dodge truck driveshaft U-joint in the repair. Those kinds of shops are pretty creative. :) |

Also had mine done at a drive shaft shop about 10 years ago. I'm about to have it done again.

Also it's my understanding that after you have the Rockford u-joints fitted, you can change them yourself (using a Rockford u-joint). |
I'm not sure what u-joint they used last time but it is pressed in. I will have it balanced at the same time. I think 10 years ago it cost me around $50, I'm guessing now it is close to $100.

It would have been easy had it not been for that damned exhaust shield covering it. I've bought some tin snips and am gonna remove it permanently todAY. I understand it's for those 3 catalitic converters, and while I was asleep one night some elves removed all 3 of them along with the exhaust pump and installed a Racing Beat exhaust system. |
On my old car, I ran a straight through exhaust so I removed the heat shields. I never had a problem with excess heat on the floor.
All the heat shields bold in so there is no reason to cut them. By unbolting them, you could always re-install them if needed. |
