    I am needing to replace the UC bushes on the old Suuz and have been quoted R 1 100 fitted by CV Specialists in Pinetown.
    They seem to have good references.
    Any comments or advice before i do this?
    Many thanks, Peter

    I haven't made up my mind yet whether PU or rubber is better for those. If the PU compound is too hard, it's brittle and breaks up. PU have better wear resistance, but rubber have better shock resistance, and that part takes a lot of shock.

    I't's a sh*tty job. Half the time they won't press out, which means you have to set fire to them. Also if the guy pressing them in doesn't know his job, the shaft gets bent. As to rubber or PU, I suggest the rubber. It's moulded in a metal sleeve, which the PU won't be. If any dust gets in between the PU bushes and the arm, it wears out quickly. Even more so when they uses rubber grease to press it in...

    Oh and just make sure there isn't any oil leaks around the area, obviously oil corrodes rubber

    It has been said many times that you should only use the GM bushes. I replaced mine with aftermarket bushes the first time. They lasted just over 2 years. Second time around I shelled out for the GM bushes.

    Lately My van feels twitchy on the road when the surface becomes uneven. It tends to track a bit on road cracks under braking. (It pulls up in a straight line if the road is flat). When you change lanes and the road is uneven it pulls a bit when you go over the "humps" left by trucks. I took it in to get the suspension and alignment checked again and was told that the upper control arm bushes were worn. They lasted about 6 months... I am pretty sure that I fitted them properly (Nuts were tightened up after the vehicle was set back on the ground). Had the alignment done which included shimming and all was within spec.

    I am apprehensive about using GM bushes again. I am tempted to buy a complete aftermarket control arm this time and see how long that lasts.

    As for that price Peter, the aftermarket bushes are around R100 each and I was quoted R450 a side to do the fitment and I needed to get the bushes pressed...

    So maybe just best to go with non-GM rubber bushes then?

    That is a decision you will have to make Peter. People still insist on using GM bushes.

    After chatting to a few people, I think I will probably give them another go just in case there was something that I did wrong last time or maybe I just got a dud batch. If they fail on me again, I'll just use pirate.

    I have a 2006 model. It is twitchy on uneven surfaces. Prices from the agents are R10850 ex for the right and R6916 ex for the left upper control arms. I stopped listening what the rubbers alone cost at that point think it was R8800 ex.

    So obviously those will not happen what are the alternatives?

    I bought the rubbers from Midas and had them fitted in Krugersdorp about 3 years ago. Have gone on some 4x4 routes and and traveled the north of Nam with no trouble at all. I am a very cautious driver.

    The single most biggest reason bushes don't last is faulty installation.

    The bush bolts should receive final tightening once the car is resting on it's own weight. Ie. the bush is not stretched/stressed at the neutral stance position of the suspension.

    If you tighten before the car is put back to it's own stance position the bush gets stressed just being in a stationary neutral suspension position. Hit a bump and it over twists/stretches and the bush fails prematurely!

    I know people talked about replacing them with poly bushes? Did anybody tried it? http://www.suspension-steering.co.za...p?productid=37
