blackbomber Posted October 4, 2019 Report Share Posted October 4, 2019 hey Guys Well i guess i a ready to do something about my power steering pump bearing..noise. every winter it gets worse and worse. so, I have bearing and seals. So . gonna get it off and see what I Got. For starters. is there a drain screw on the steering gear box??. do I have to drain the PS fluid first??. Not having much luck finding a video on you tube. My truck is a 1984 4x4 2.4 L ..... Thanks 1 Quote Link to comment
bottomwatcher Posted October 4, 2019 Report Share Posted October 4, 2019 Getting the pulley off is the hardest part. Otherwise just a snapring bearing and seal. Last time I did one I bought the bearing and seal using their numbers for about $15. Rebuild kits using the same parts I think was north of $60 and rebuilt pumps over $100. I just disconnected hoses and put rags on the ends. It wasn't a big mess but I have a remote resivior on mine. If your reservoir is attached drain the low pressure side. 1 Quote Link to comment
blackbomber Posted October 5, 2019 Author Report Share Posted October 5, 2019 Hey guys. this sucks.. I got the pump detached but it wont come out. manual says theres 4 bolts total. 2 on a bracket, a nut and bolt in front. I can get it to move up and down. its like wedged. or something.. the lines are still on it, have not disconnected, but I don't think that's it. my arms finally gave out trying to rock it back and forth.. 1 Quote Link to comment
datzenmike Posted October 5, 2019 Report Share Posted October 5, 2019 Are you sure it's the pump? and not the pulley and bearing used to adjust it? If the belt is off give the adjuster a spin by hand. Any roughness will make noise. The pulley tightening bolt is left hand thread. 1 Quote Link to comment
Stoffregen Motorsports Posted October 5, 2019 Report Share Posted October 5, 2019 Does the bracket have those bushings that tighten against the pump when you tighten the bolt? You know, like on an alternator bracket. If it does, those bushings are designed to wedge it tight. Just use a pry bar to get the pump out of the bracket. Be careful what you pry on though. Of course, I am assuming you have all the bolts out. Mike has a point about the idler pulley. For some reason, when it's wet out, some idler pulleys get noisy. If the noise is there when you cold start it, but goes away when it warms up, it could be the idler pulley. If the opposite occurs (no noise on cold start then noise when warms up) it's likely the pump. 1 Quote Link to comment
blackbomber Posted October 5, 2019 Author Report Share Posted October 5, 2019 I know guys. I have been diagnosing this for a while and last year I decided it was the pump making the niose, I had a stetha scope on it numerous times and the noise was definitely in the pump.. if I am wrong so be it, but that my conclusion. I wanted it to be the adjuster pulley, believe me. I have the bearing and seals for the pump... If I cant do it, I will just have to get a rebuilt.. After I take a nap,, gonna get the frikkin thing out!! 2 Quote Link to comment
blackbomber Posted October 6, 2019 Author Report Share Posted October 6, 2019 Ok guys looks like my original Nissan manual is wrong again.. that manual is really junk. So theres another bolt in front that was holding it in. Got the pump all apart... And uhh yea . gonna take seal out tomorrow. but I don't see any way there is a bearing behind it, but we will see. shaft just runs in a lubricated tunnel. I know the seal has been leaking for a very long time. Could the leaky seal be making the noise on the pump??? or the casing for the shaft isn't staying lubed.?? because of leaky seal 2 Quote Link to comment
blackbomber Posted November 22, 2019 Author Report Share Posted November 22, 2019 Hi guys. just wanted to get back on and follow up on what I found out about the power steering pump. I got the leak fixed. no bearing in there. just a nylon sleeve with grooves in it. the power st fluid runs in the grooves and lubes the pulley shaft. so when I parked the truck at night, the fluid would leak out around the seal , then when it was cold out and I would start it, it would squeal really bad for at least 5 to ten minutes until more fluid got into that shaft.. so .. just wanted to share that little bit of info... 2 Quote Link to comment
