Jonatsun Posted June 6, 2014 Report Share Posted June 6, 2014 Hello, so i was driving my baby, 1979 620 when i hit a pothole going down a hill. Alignment shims where falling like tic tacs out of the bottom so i took it to a shop and the mount to the front left control arm is broken. they wanted to charge me upwards of 700 dollars. but its my rat, I've done all my own work in the past so i took it home. Now i cant find control arm mounts for my rig, i searched this site and others but cant find the process of what to do and i need it running within 2 weeks. does anyone know where to find these mounts or substitutes? i live in spokane washington its the lower control arm Quote Link to comment
datzenmike Posted June 6, 2014 Report Share Posted June 6, 2014 These parts don't usually fall out, so what did you do to it?? Keep in mind that pictures help.... Quote Link to comment

Keep in mind that pictures help.... i hit a pot hole and the mount broke and then it allowed space for shims to fall out, then they kept gradually falling out on the drive home, i cant post pictures. dont have ability right now, no cellphone or digital camera Quote Link to comment
flatcat19 Posted June 6, 2014 Report Share Posted June 6, 2014 Cut them off of a scrap yard car, weld to yours. Contact Beebani, see if he can make you new ones to weld on there. Call a metal fab shop to copy the other sides, weld to frame. Go shopping for a new car. Quote Link to comment
]2eDeYe Posted June 6, 2014 Report Share Posted June 6, 2014 Hard to say without seeing exactly what broke, if it is the frame mount you will need a fabricator. Quote Link to comment
datsunaholic Posted June 7, 2014 Report Share Posted June 7, 2014 If the part that broke was welded to the frame, $700 isn't an unreasonable amount to weld on a new perch and realign everything. If it's just the bolt on part, then it's junkyard hunting time and you can do it yourself. Though if the shims fell out, I'd think the threads got stripped out. Quote Link to comment

yello620 Posted June 9, 2014 Report Share Posted June 9, 2014 its the lower control arm i hit a pot hole and the mount broke and then it allowed space for shims to fall out, then they kept gradually falling out on the drive home, Interesting what could be broken here. The lower control does not have any shims...The upper does though.... Quote Link to comment
datzenmike Posted June 9, 2014 Report Share Posted June 9, 2014 This is what happens when a vague post is made that begs more questions than answers. You need it running in 14 days and 4 have been wasted. I picture often shows the problem even if the question is wrong. A pot hole isn't going to do what you have described. Quote Link to comment

It would if the frame was rusted enough or maybe it was crashed before and not repaired correctly. Either way we would need to see the problem area, til then it's all speculation.

Jonatsun Posted June 18, 2014 Author Report Share Posted June 18, 2014 no shops in town have this part or can order a mount for a 79 620. What other mounts might fit on the 620? so i can go to a scrap yard. if you need better look from different angles let me know Quote Link to comment

ggzilla Posted June 18, 2014 Report Share Posted June 18, 2014 1. On photobucket, copy the IMG Link 2. Paste it here in Ratsun This is a special shoulder bolt. Use a high-strength steel replacement from the auto parts store. Quote Link to comment
datsunaholic Posted June 18, 2014 Report Share Posted June 18, 2014 Maybe it's just my eyes, but I can't see the broken part. Yes, things aren't where they are supposed to be but it just looks like a truck that's been lowered too far with no suspension travel, resulting in the bump stop getting bent and a bent LCA.. If the broken part is welded to the frame I don't see you fixing this yourself. If it's one of the bolted parts, then you just need to replace it, though that LCA looks twisted to me. 78-79 620s are your only option there. A view from under the hood from above (with the rubber splash shield pulled back) , or from the side with the wheel off might tell me more. I just can't see what's broken from those angles.

MicroMachinery Posted June 18, 2014 Report Share Posted June 18, 2014 $700 to replace a bolt and some shims? Geez.. I need to open up shop in Washington.. 1 Quote Link to comment

datzenmike Posted June 19, 2014 Report Share Posted June 19, 2014 Nothing wrong, I'm with Doug on this. These bolts don't back out. Someone had them out to remove shims to adjust the camber after dropping it way too far and didn't torque them enough. They were already loose when you hit the bump.The Nissan part number for the '78-'79 620 is #08104-44510 and is an M 14X1.5 hex bolt about $3. Also used on the 2 and 4wd 720 truck through Oct. '82 Get some lock washers for it and torque them properly. Needless to say (but I will anyway) check the other side right now!!! 1 Quote Link to comment
LenRobertson Posted June 19, 2014 Report Share Posted June 19, 2014 If you can't get new bolt from Jaremko Nissan parts in Spokane (and the guys there are really good to work with), go to the two Pull & Save locations: http://www.pullandsave.com/home.htm Their inventory shows '80 and '81 pickups at the Valley location. The North store probably has something too, but the website is being weird tonight and doesn't show inventory. The inventory lists aren't always up to date anyway, so take your tools and go see what they have. Len Quote Link to comment
datsunaholic Posted June 19, 2014 Report Share Posted June 19, 2014 As long as that's not a crack in the tower (probably isn't), should be able to replace the shims and bolts. Replace both- I can guarantee the other one is bent. Hopefully the threads didn't get stripped out of the tower. But that's caused by the bolts backing out, the pothole just aggravated the problem. It was going to fail pretty soon anyway as the bolts backed out more. Parts that aren't supposed to move started moving, and the momentum was more than the bolt could handle. Usually when that happens both bolts break and the upper A arm ends up in the oil filter, so you got lucky there. Quote Link to comment
