Guibo question - BMW Forum

BombSquad91 · 08-06-2009, 07:37 PM

Here's my situation: My guibo is shot. It's the 3rd one in 4 months. I installed UUC solid tranny bushings. Normally these wouldn't be a problem, but before I got the car there was bad frame damage. The combination of the frame damage and the solid bushings kills guibo's. I'm getting rid of the car in a few months and getting a '95 35is. I'm gonna strip this one and put some parts on the new one and save some. I don't want to buy a new guibo or stock tranny bushings. I don't want to put ANY money into the car. I thought of a quick fix. I'm going to cut 2 circles out of a piece of 16 gauge steel and drill 6 holes in them. I'm going to put one circle on each side of the guibo. WHat does everyone think of this idea as a TEMPORARY fix??????

I would have to say fix it right the first time and you don't have to worry about it agian. I learned that the hard way with my first car.

You keep replacing guibos - that indicates bad shaft alignment, or mismatched tranny and rear end...

In Asia, where parts are hard to find... You can fashion one out of conveyor belt material using ur original guibo as a pattern. Depending on how thick your material is, you may have to make 3 or so... It's definitely more durable than the original. Your fix just won't work... you need for the shaft to play longitudinally and laterally while the suspension "plays".

But, why go that way??? Time vs. money analysis will tell us, it's cheaper to buy 2 guibo's over using up time to fabricate 1 + the material expense

Cheers

The guibo is made out of rubber for a reason: to be the weakest part in the drivetrain so that you don't tear up the gearbox or the driveshaft. You make it solid, you're pretty much guaranteed to destroy something else (might not happen immediately, but it puts a lot more stress where it wasn't designed to be).

Well, I did it the right way and it shredded the guibo again. So now I did it my way. The first pic is of my guibo shredding progression.

nice work, so did this solve your guibo problems? as Torque said you're going to grenade something else if your fix holds up. i'd be gettin on buying that other car

btw, how are you driving this car if you're shredding guibos like that? Under normal (or even agressive driving), it should last tens of thousands of miles.

edit: Still not a fan of the fix. I wouldn't be surprised if you now move from shredding guibos to demolishing the center bearings (which are quite a bitch to replace in comparison).

+1!!! Congratulations on now being the owner of a time-bomb! Glad I won't be behind you when parts start grenading...

Replacing a guibo is a whole lot better than replacing a tranny or something else. The guibos should be rubber and rubber only. They need to flex and take abuse as well as add play to the drivetrain. If the guibos keep getting torn up there is a problem somewhere else.

BombSquad91 · 09-14-2009, 10:03 PM

The guibo's keep shredding cause there is frame damage from before I got the car. And as far as flex goes I used 16 gauge sheet metal. It's not high grade steel. It won't give as much flex as the guibo but it will give a little flex. If I had a guibo fabricated out of titanium THEN everything would start blowing up.

Screw the titanium, Go Nuclear.....Titanium & Plutonium Guibo!

I'm also thinking about replacing my shocks and springs with a solid steel rod. It will completely eliminate body roll.

ROLFLMAO! you remind me of a young guy I knew about 5 years ago. He's a very successful custom car builder these days, but he wasn't afraid to think about doing anything to a car!! And he usually did it too! He's an interesting chap. (but dangerous..)
