Hi,

Have a spare gearbox for a 1995 164 3.0 24v, with an inch hole in the diff casing where the diff blew.

Understand the gearbox itself was great before the diff let go, so wondering if a Q2 limited slip diff could be purchased to replace it and the casing repaired. Have heard some Q2 gear grinding required to get the speedometer to work properly with it.

Any advice?

Hi,

The casing was punched through at very low speed. The pinion on the diff had broken and dropped down in the diff, jamming it. The garage crew force pushed it to get it on a ramp and that was when the casing went. A significant hole but don't think at a structural point, hence thought it could be repaired.
In worst case, have possible access to a second 24v box with other issues to steal the diff casing from that. Can these just be swapped over?

Thanks for the help.

When the diff pin backs out it impacts the center of the bellhousing not the diff case. I seriously doubt the bellhousing could be relied upon ever again, even with serious cast aluminum welding skills. If you have access to a whole nother trans, just put a Q2 in it. A later model trans is supposed to be engineered stouter so that would be a preferred gearbox to have anyway. If it has other issues, than think about having it repaired. If it is in one piece it is already an improvement over what you have. I have pics of the type of damage resulting from this failure in threads I have posted regarding the issue and you will be able to see what I am talking about.

Was yours inpacted differently?

Thanks, Charles.

Because mine went at walking pace while the mechanics were pushing it the hole in mine is, I think, in the diff housing. Will take a pic over the weekend.

Cheers.
